New Toy: Meet the Wobbleometer(TM)

Posted on 2024-02-13 by spodzone

I’ve had my eye on the Raspberry Shake seismometer for a couple of years now. Last week, I finally succumbed and bought both a new Raspberry Pi (just a 4B 2GB RAM – cheap yet more than adequate) and a Shake 1-D.

The 1-D is a simple seismometer, responding only in the up/down direction. Other products are available…

Mine arrived as a kit, that even I was able to stick together in under half an hour (thanks to a youtube video showing what most of the screws and things were for).

I installed and levelled it on the downstairs windowsill and plugged it directly into the main ADSL router – when you’re uploading a hundred samples per second, minimizing latency is essential.

Obviously, being based in mainland Scotland, I don’t expect to see that many significant earthquakes. We get a handful of ~magnitude 2.5 around the country every couple of years if we’re lucky. However, recently YouTube has sent me down a rabbit-hole of geological analyses of goings-on in Iceland’s Reykjanes peninsula – the recent sequence of volcanic eruptions alternating with tiny earthquakes as the magma chamber refills.

The very first night, I spotted a magnitude 3.6 quake in Iceland.

Since then, the live data stream has sadly been unavailable for about 5 days, but when it works, the ability to select a quake event and then click on a station and see the station’s raw data really rocks.

There was another magnitude 3.7 earthquake along the Mid-Atlantic Ridge offshore a few miles south-west of Grindavik yesterday. The live-data view is currently working in the mobile app, leading to this analysis – showing the P and S waves propagating from the event.

As monitoring equipment goes, I’m impressed. It’s a wonderful device, very sensitive yet easy to set up and works well. I’ll continue to watch for all quakes nearby and larger ones further afield, if only to be able to say “I saw it” 🙂

Mallaig Circular and Loch an Nostarie

Posted on 2021-09-04 by spodzone

On a whim, I spent my August bank holiday out and about exploring a new location: on the far west coast, Mallaig is home to the ferry port connecting to Skye.

Just to the south of the town lies Loch an Nostaire – a lovely shallow loch of clear pure water and indeterminate name etymology: the current spelling is clearly anglicised, although there are no mentions of the more obvious Gaelic Nostaraidh, but rather variations include “Nosaraidh” and “Nossery” according to the 1852 Admiralty Charts. One option is for the name to date back to Old Norse naust, a ship; an alternative derivation might be via Gaelic nòsar, juicy, sappy, white. This would be cognate with nòs, cow’s milk, which sits well with one of the tributary burns being called the Allt a’ Bhainne.

The Mallaig Circular walk leads from Glasnacardoch just off the Rathad nan Eilean inland to the loch, then up between the hills Creag a’Chait and Cruach Mhalaig before descending to Mallaig.

The view down the loch, especially from higher up, is beautiful: to the east the hills of Cruach Clachach and Cruach Bhuidhe are quartzite outcrops forming a backdrop behind an unnamed island on the loch covered with native Scots Pine trees; along the opposite side of the loch runs a prominent ridge where Morar schist pelite changes to psammite.

Classic landscape: small rocky boulders in the foreground, an expanse of grass, and the loch and hills beyond under a clear blue sky.

Assynt, Day 2: Solus Na Madainn

Posted on 2019-08-21 by spodzone

For the second day of my holiday last Autumn, I got up – again! – at a ludicrously early hour and drove from Tongue round to the Assynt peninsula, to my favourite viewpoint for sunrise.

It was some drive.

All the way from Tongue to Loch Assynt without seeing another car. Bliss.

Take the A838 road (abused as part of the ghastly NC500 coastal route) via Durness at 5am in the pitch black, the wind blowing a gale, rain + windscreen wipers on full speed.

Picture avoiding a herd cows intruding across the road. Avoiding more than 10 deer.

At that surreal pre-caffeinated hour of the morning, seeing a signpost advertising “serving local seafood” makes me picture a restaurant waiter taking a scallop’s order at table.
The music of choice was Arcade Fire Mountains beyond Mountains – a song bemoaning city life with its world so small – a mental image contrasting with my surroundings, passing rural Scourie, pop 132 – the sort of place that takes longer to say the name than drive through.

And so I arrived at Rhicarn – the landscape black, clouds a grey plasma, just a little bit windy…

And the sun rose. Quite spectacularly, casting brilliant crepuscular rays from the horizon and underside edges of clouds.

A brilliant display of crepuscular rays, shadows coming from the edge of a cloud as the sun rose beside Canisp.
Beautiful morning light: crepuscular rays streaming from a cloud edge, illuminating the sides of Suilven and Canisp and the Manse Loch in the foreground.

Throughout the sunrise, the light was spectacular – brightly illuminating colourful clouds.

Simple abstract patterns: bright early morning sunlight illuminating clouds a warm yellow/orange.

…and casting a subtle hazy glow over the morning fog across Little Assynt, outlines of hills receding into the mist

As the sun rose, the ground heated just enough for the overnight dew to evaporate into a thick fog, filling the landscape enough to obscure the receding lines of hills into nothing but a bright haze beside the sun. Manse Loch / Loch Uidh a’Chliabhain remains clear, a mile into the foreground.
Iconic Scottish landscape: the Manse Loch and layers of hills and mountains receding into the hazy distance

Perhaps my favourite image from the morning has to be Suilven, the unmistakable mountain on the horizon, catching a subtle patch of oblique sunlight on a flank.

The unmistakable shape of Suilven (Sùilebheinn) catching an oblique beam of warm early morning sunlight.

Once the sun rose, I explored the Falls of Kirkaig outside Inverkirkaig. A nice long walk through lumpy landscape, to a large thundering waterfall.

Undulating landscape; gneiss outcrops amongst the grass and heather beside the path above the River Kirkaig gorge.
An impressive waterfall – 60ft tall and flowing deep and fast into its splash-pool below. It’s also one of the scariest places I’ve been in a landscape; this view is from a small platform area, a steep descent down the left face of the gorge. With my own dog for company there was limited space even to turn around and plant the tripod and camera bag.
As if the river Kirkaig wasn’t full and fast enough in the bottom of the gorge, walking back along the top the clouds were pretty dramatic, the light behind coming through as crepuscular rays above the silhouetted hills.

Returning to above Rhicarn, clouds had flowed in obscuring the mountains on the horizon, so I experimented flying the drone to admire the surrounding landscape.

There’s something about finding a thin strip of old tarmac that obviously used to be a road – it makes a connection with the story and heritage of a location. From researching on Pastmap, it appears there was not much road here at all throughout the 19th century – presumably a cattle drovers’ track or similar. Then the old tarmac was laid, following a circuitous path around the gneiss rock hills. Finally, some time after the 1960s, a new road, now the B869, was laid through it in a boring straight line, the old route relegated to a carpark yet visible and walkable either side of the road.

I suspect at one stage this might have been nothing more than a cattle drover’s track down to the lowlands, maybe up until the early 1900s; up to 1960 the road was just a thin narrow track of tarmac with a couple of moderately sharp twisty turns in. Since then the B869 has been rerouted into a simple and less inspiring straight line and the old road relegated to a path, some of it widened to form a carpark beside the new. The bedrock is mostly Scourian gneiss, metamorphic, formed 2500-4000 million years ago (and therefore amongst the oldest rock to be found on the planet); down the centre of this view is a line of Lewisian metagabbro, gneissose, also metamorphic, formed 541-4000 million years ago. I’m not sure what the large central depression might be – it looks rather like a quarry, although there’s no evidence of anything on the maps.

Behind this scene, on the way to Clachtoll, lies some beautiful Karst landscape (cnoc’n’lochan or knock-and-lochan), formed by underground erosion of softer rock, leading to a classic pattern of rocky knolls interspersed (almost 50-50 by area) with lochs.

The joys of knock-and-lochan Karst landscape: it’s almost all equal parts gneiss rocky outcrops and lochs with roads wending their way through the shapely landscape.

Further along the road lies the Maiden Loch, of which I’ve been very fond since first catching sight of it years ago. That first view was on a sunny afternoon, the sky blue reflecting in the water. I flew the drone over it, to admire the gneiss landscape all the more…

Fantastic scenery: Assynt at its very best. A very windy moment flying the drone above one of my favourite lochs, the Maiden Loch near Clachtoll. The landscape is typical knock-and-lochan Karst formation: shaped by the dissolution of a layer or layers of soluble bedrock, small undulating gneiss hillocks emerge amongst the lochs. In the hazy distance, Suilven cuts its familiar outline on the far horizon.

Smirisary

Posted on 2019-08-07 by spodzone

Can’t beat Scotland’s West Coast in summer. Saturday was spent exploring a new place to me, Smirisary in Glenuig, Lochaber.

A beach of large psammite outcrops with lyprophyre dykes

Cracks and sedimentary strata lines in an exposed lump of psammite, Smirisary.
Erosion in action: an exposed lump of psammite (metamorphosed former sandstone) showing lines of strata and cracks, with gentle folding, yet surrounded by stones and boulders where the sea has eroded it away.

A perfect subject for an abstract art: dense close strata layers of psammite (mid/coarse-grained metamorphosed sandstone) tightly packed.

Signs of habitation – old (but possibly still in use) croft/houses just above the shore in amongst the caves

Signs of settlements – Smirisary forms a small cluster of houses down around the shoreline, nestling amongst the rocks.
Evidence of former habitation. Just because the west coast has its culture and traditions does not mean we should refrain calling out an example of litter for what it is in the context of environmental pollution. Discarded metal bath-tub and other crap in a cave-mouth, Smirisary.
A beautiful beach – ideal for a paddle in the shallow seas with Dog – surrounded by rocky cliffs.

Beautiful landscapes – wide vistas via light on the sea out to the islands of Eigg and Rùm on the horizon

Sunlight playing on ferns in the foreground, looking out to the islands of Much, Eigg and Rum with their distinctive mountain outlines on the horizon.
Sky meets sea in an atmospheric haze of glowing light. Very ethereal.
Dramatic light: crepuscular rays emanating from dark clouds over the islands of Eigg and Rum across the water.
A variety of types of cloud billowing gently over the distinctive outlines of Eigg and Rum on the horizon.

And on the way back home we called in at Loch Eilt by the roadside – partly to wash the salt water out of the dog, but also to admire the symmetrical reflections. The midges were out in force, pesky and biting as ever, but the photos were worth it…

Pure green: Scots Pine trees on an island across Loch Eilt. Pleasant clear and pure water. Shame about the hordes of midges – some flying so close to the lens I could see them larger than life on the live-view screen. A combination of long exposures sufficed to remove them, however – this is a combination of HDR (5*±0.7EV) and pixel-shift (4*1px offset) for optimal dynamic range and resolution.

Concerning Rocks

Posted on 2019-07-31 by spodzone

Some years ago I had a passing interest in the abstract shapes and forms rocks can take.

Recently I was out on the Aberdeenshire coast hunting photos with a friend, who, being impressed with the rocky coastline, wondered exactly where the Highland Boundary Fault emerged at its most north-eastern extremity.

After a bit of research (particularly exploring using the BGS‘s iGeology app), I tracked it to a small headland, Garron Point, beside the golf club outside Stonehaven.

From the outside it doesn’t look like much, but on closer inspection it is awesome.

There are actually two faults – a small one at the north-eastern end of Craigeven Bay corner with Garron Point, forming a small spur off the Highland Boundary Fault which clips the coastline from the town out to sea.

On the lowland side the bedrock is metabasalt, psammite and pelite (North Esk formation) – metamorphic bedrock formed around 461-485MYa in the Ordovician period. On the highland side is gritty psammite (Glen Lethnot grit formation) – around 541-1000MYa.

The fault itself can be tracked to a matter of a few feet – a view from beside one of the golf greens shows the junction of both faults, with a strip of incredibly deformed grey rock leading away some meters rather like a line of chewing-gum.

Some of the most impressive rock outcrops I know. Toward the top-right of the frame – those cliffs are tall, especially from below! – a small fault runs diagonally down to the spray of water and out the left side; from front to back, a line of deformed pale grey rock only a foot or two wide, twisted like chewing gum, marks the Highland Boundary Fault at its most narrow only metres away from its most north-eastern extremity on land, at Garron Point headland near Stonehaven. The gnarly shapes of psammite (metamorphosed medium-grained grey former sandstone) and micro-basalt are awesome.

Prior to metamorphosis, this used to be sandstone. Now it forms a medium/coarse-grained rock, pale blue-green in colour, along the line of the Highland Boundary Fault.
This boulder marks the intersection of two fault lines; a small one, running diagonally from top-right to bottom-left, and the Highland Boundary Fault, running front to back. The zoom lens has compressed perspective, but for a sense of scale, the foreground rock in the right is maybe 15-20′ away.

My favourite image is an abstract closeup – purply-red microbasalt meeting gritty blue-green psammite in a spray of cracks and marbling lines.

Prints are available on my ShinyPhoto photo gallery: Under Pressure

Perhaps the clearest view into the workings of the Highland Boundary Fault I can think of. On the left, red-purple microbasalt (its fine cuboidal structure putting me in mind of streaky thick bacon); elsewhere the blue-green-grey of psammite and pelite, medium- to fine-grained metamorphosed former sandstones. All jumbled together with fine cracks and lines of marble hinting at the pressures involved.

Gear Change Time

Posted on 2018-08-14 by spodzone

Back in May I had a bit of a holiday. Figured the primary camera would be occupied taking timelapse video sequences for a couple of the evenings, and what happens if I find something else to take a photo of? So a friend suggested I get a Fuji X-T20.

Loved it.

Sold the K-1 dSLR and all the other Pentax kit, bought a Fuji X-H1 and some nice lenses to augment it.

Having spent all last Friday having the day off for the purposes of swapping the gear, I called in at Portknockie to make some photos of the well-known Bow Fiddle rock. The tide was low, requiring more care scrambling over the rocks.

Getting a bit more artistic, a long exposure view of the clouds passing by and a toned and tweaked edit:

The Zeiss 12mm f/2.8 Touit Fuji X-mount lens is a beauty. Being for APS-C crop-sensor only, it’s comparatively small, but elegantly formed with the curves flowing from lens-hood to body where the aperture and focus rings are smooth rubber perfectly integrated into the body.

I still maintain the most interesting views are to be found within the caves beside Bow Fiddle, not just staring at the lump itself. This is the first test image made with the Zeiss lens – sitting inside one of the caves, looking out, an HDR composite of 5 frames ±2/3EV each and even so it took a delicate touch getting the best RAW conversion and blend (haven’t used LuminanceHDR in ages!).

Testing my newly acquired Zeiss 12mm f/2.8 Touit lens – inside one of the caves looking out, of necessity a 5-shot HDR ±2/3EV. That lens is awesomely sharp, even with slightly elevated ISO around 640-1600.

Finally, one to relax with: the most serene simple composition of blue-grey sky with warm crepuscular rays spreading from behind a cloud. Light and sea, what more does one need?

Beautiful simplicity: a very cool blue-grey sky with orange crepuscular rays in the distance.

when a landscape location goes sour

Posted on 2018-05-11 by spodzone

I don’t know how to tag some of these photos: on the one hand, a place that’s been a good walk in the trees for over a decade, but on the other, one that’s now showing the tarnish of human influence. Landscape photographer’s idyll or sad anger?

The Falls of Bruar present several well-known scenes. My own story is of having bought a tripod to do justice to a particular view and then using it to shoot a “hole in the ground in failed light” instead, thus getting one of my most-popular photos on flickr. I’ve been back probably 10 times over more years and enjoyed the stroll up the side of the gorge, admired the rocks, watched the three waterfalls doing their thing.

First there’s the regular cliché photo approaching the lower bridge – everyone gets the view from the top of the gorge opposite the lower bridge; I flew the drone down into the gorge and shot it from more on a level with the natural arch:

Nice rocks – psammite and semi-pelite as most of the Highlands, with the shear strata arising from the end of the Loch Tay fault-line.

Around the corner, there’s a viewpoint amongst the rocks of the second waterfall above the lower bridge:

Rising above the gorge one can see the pine trees lining the Bruar Water – it also shows how the middle cascades extend much further upstream than might be expected from the compressed perspective of ground level:

Abstract view of the lower Falls of Bruar

However, this visit was far from happy. Apart from some offensive uncouth ned muttering “hope you lose your drone” as he passed by, and the hordes of random unwelcome people thinking they were entitled to pester the dog, there are massive botanical problems: the two bridges have been closed so the path up the right side of the gorge is inaccessible due to tree works – possibly because of disease although I’m unconvinced this is the whole reason.

Bridge closed

Walking up the left side of the gorge instead, the area is infested with non-native invasive rhododendron bushes; the Forestry on the adjacent hillsides has been harvested leaving a horrendous unsightly barren landscape; the burns and tributaries beside the path are in a dire state of disrepair also.

Who wants to walk along here?

This is the trouble with well-known landscape locations; as photographers we like the illusion of wilderness, or at least that places are natural. Bruar has become no more than an ill-kempt garden with a water-feature running through the rockery. The light and shade and calming deep greens are no more to be seen.

I’m giving it a decade to recover before revisiting.

The Far North

Posted on 2018-04-12 by spodzone

The intended road from Rosal due east was closed for road-works; I took an incredibly long detour all the way to the far north coast of Scotland – next stop the Faroes and Greenland – and stopped at Portskerra to make a couple of long exposure landscapes as the light faded to dusk.

The coastal geology was impressive – alternating areas of gneiss and sandstone with clear strata in the rock.

Autumn Holiday Day 2: Assynt: Rainbows, Rocks and Stories

Posted on 2018-02-03 by spodzone

The first day of the holiday was spent in Glen Affric and working my way up to Rogart; on day 2, the weather looked best to the north-west so I drove over to my favourite Assynt for the day.

Assynt: Land of Rainbows

Even before I’d got in the car, I saw the first rainbow of many across the glen:

A sign of things to come: before leaving the lodge for the day, a nice rainbow appeared along the glen.

The road was every bit as narrow-veering-nonexistent as I remembered – always makes journeys feel that much longer than the mere count of miles covered – and increasingly the previous night’s snow-fall intruded onto the edges of the tarmac. Good challenging fun.

I only stopped once to make a photo of Ben More Assynt from across the landscape:

The first snow of late autumn covering Beinn Mor Assynt, illuminated in a nice pattern of dappled morning sunlight.

As I passed Inchnadamph heading toward Loch Assynt, the weather turned very mixed – phases of sunshine and hail alternating every couple of minutes – with some fantastic rainbows. It didn’t take long waiting in a layby before another one illuminated Ardvreck Castle – drive around the corner of the loch and walk down the castle and in next to no time, behold another rainbow. You certainly learn to read the signs pretty quickly – as soon as a bow appears, put your jacket hood up as the rain will be along shortly.

I also took a couple of photos of the Inchnadamph Caves, a distinctive rock formation on the Moine Thrust zone, in which bones of Eurasian lynx, Arctic fox, reindeer (dating back 47,000 years), polar bears (the only evidence of their presence in Scotland) and humans (back to 3000BCE) have been found:

Continuing north up the B894 a little way, even in dull cloudy light the surrounding mountains were beautiful, sprinkled with a heavy dusting of snow. I stopped at Loch na Gainmhich and explored around the frozen peat-bog by the roadside a bit:

Sky above
The bulk of Glas Bheinn across
Loch na Gainmhich filling the corrie
Peat bog covered in heather
Frozen puddle
And it wasn’t even winter yet – just the first snows of the season giving a thick dusting coat over the mountains. With the sun hiding behind clouds, the light was a beautiful dull grey.

Turn around and what do you know, but there’s another vibrant double rainbow seemingly making its way over the landscape as well:

I stood beside at the top of the hill beside Loch Gainmhich looking over the undulating landscape to Loch nan Eun, watching the rainbow and its secondary bow evolve.

Assynt: Moody Wailing Widows

Having seen photos online of the Wailing Widow waterfall very near to the road, as the Allt Chranaidh leaves Loch na Gainmhich, I spent hiked over to the edge of the loch and, faced with a stiff wind and slippery frozen peat-bog underfoot, decided it wiser to approach the falls from the bottom of the 30m gorge instead. Not the easiest terrain either way – many large boulders, some slipped down from the sides of the gorge, requiring scrambling to cross with tripod and camera gear. From the little carpark barely off the road, there’s just a moderate river running away:

I’ve visited Assynt several times over the years but was quite surprised to discover a “new” waterfall via various online contacts, and one right by the roadside at that.
There is a track to the top from round the corner in the road, but a hike across frozen peat-bog in high wind was not the safest so we approached from the bottom of the gorge instead.

The first sight of the falls is quite starkly atmospheric:

I made it quite close to the splash-down, where it was tricky taking photos for all the spray covering the filter:

In Assynt, you can’t even sit down in the driver’s seat without admiring the landscape – in this case, as the clouds passed overhead a small gap let a little light illuminate the flanks of Quineag, grey rock dusted with snow:

A view from the car window, of all places – just as I was preparing to drive off, this little patch of light on the great snow-covered grey sides of Quineag caught my eye.

From Unapool I drove back along Loch Assynt and out into the Stoer / Clachtoll peninsula, some of my favourite rugged landscape.

Assynt: Land of Heritage

The area around the B869 fairly reeks of history. Starting way back, the geology is awesome: gneiss bedrock (two kinds – Lewisian and Scourie group) interspersed with several minor fault-lines and the Scourie dyke swarm (metamicrogabbro).

This makes for a lumpy cnoc and lochan landform characterized by many rock hillocks interspersed with lochs and lochans in between.

Some of my favourite landscape, absolutely typical of the north-west coast of Scotland: Gneiss, in this case from the Scourian group dating anywhere from 2.5 to 4 billion years old; originally igneous but also subject to later metamorphism.
This whole part of the Assynt peninsula, enjoyed by the “loop” road B869, is a large swarm of metamicrogabbro and amphibolite dykes (formed 1.6 to 2.5 billion years ago).

On a sunny day, the blue sky reflects beautifully in the lochs by the roadside; however, this was not to be this time. Behind the above photo, the road continues wending its way around sharp corners and up and over a rise to one of the most awesome viewpoints I know, with five mountains of Assynt spanning the field of view along the horizon. The weather was not the greatest – rather than a clear vista, there were clouds rolling across the landscape from behind, intersecting with mist rising off Suilven.

Spending a couple of hours standing watching the scenery (and occasionally getting rained-on in the process) afforded me time to ponder the road in front. Travelling up the B869 there are a couple of tracks to either side with entrances blocked by boulders. Obviously there used to be an old route – very narrow at barely a car’s width, with a couple of sharp S-bends, tarmac degrading and obscured by heather/bracken/undergrowth – and the new tarmac has been laid in a much straighter line, with the viewpoint carpark repurposing some of the old route. It makes me wonder what the place would have been like one or two centuries ago, how the road might have evolved from a drovers’ track or similar.

Suila Bheinn

I walked along as much of the old road as I could find, conscious of a sense of heritage and change in land usage.

There’s a shrine on an Assynt hillside
Made of earth and salt and rain
Now you walk out in the morning
With your sacrifice of change

Assynt: Tasty Colour

Having heard about the beach nearby I left Rhicarn and explored a different road, to Achmelvich.

On the way, the sunset was stunning. A brilliant red-orange ball floating above the horizon, offset against the cold slate-grey clouds and paler blue water of Loch Roe. Even partially obscured by cloud, the colour contrast was awesome – and with a whiff of sea-salt on the breeze, put me in mind of a west-coast single malt whisky…

Driving the last stretch of the road to Achmelvich, the sun set right in front of me, a large orange-red ball above the water. The combination of colours, cold blue slate grey sky and warm yellow-orange heather, coupled with the sea breeze put me in mind of a fine west-coast single malt whisky…

The only real downside of the day was Achmelvich itself. The beach at the end of the road is very pretty, clear pale sand, the water beneath the waves’ foam having a beautiful clear blue-green colour. However, the beach is surrounded by a ghastly caravan park which in itself suffices to detract from the scenery. The place is littered with anti-dog signage – at one point I counted no fewer than 6 signs in visible sight with a picture of a dog saying the animal “doesn’t know better” concerning handling of litter, followed by several “dogs on leads” and “no dogs beyond this point”. I found the attitude quite aggressively hateful and will not certainly not patronize the caravan park because of it.

Still.

The light of the world keeps shining
Bright in the primal glow
Bridging the living dust to dust
Such a long long way to go
– Runrig, Saints of the Soil

Assynt: By Night

Having finished with the southern half of the Stoer/Clachtoll peninsula, I made my way back to Rogart for the night, but passing along Loch Assynt in the dark I had to stop and take a photo of a cluster of Pine trees near the shore. With a sufficient and necessarily long exposure (2 minutes!) to register anything, I like how the trees look almost stuck onto a smooth silver surface.

My fondness for the area – its geology, its weather (however extreme it felt!), its light and its rugged landscape remains unabated.

Above the Highland Boundary Fault

Posted on 2018-01-11 by spodzone

About 3-4 years ago, I first visited Birnam Hill. Made it around Duncan’s Hill to the south and through the woods… As I walked a path between old and new forestry, I wondered why there was a sharp drop down almost a metre to the level of the new trees.

Over subsequent visits I took a few photos, came back and took geotagged photos, all around the same area, went to the BGS, imported bedrock data via KML into Google Earth, correlated with the photos… After a couple of years I’m confident that the dip in the landscape is evidence of the Highland Boundary Fault – a line that runs all the way from Arran and Comrie to the south-west, through Stare Dam and Rohallion Loch and lodge, up along this dip between the trees and away to the east before heading off north-east to near Stonehaven. From a suitable angle it looks like someone’s taken a bicycle tyre and run it over the landscape, causing an impression relative to the surrounding hills and mountains.

Apart from that, the scene from Stair Bridge Viewpoint is highly photogenic and while I’ve made several photos of the view south and east since, I’ve always wanted to fly a drone along the line of the fault.

A few days ago, the dream came true: a perfect clear dry bright sunny winter’s day, snow lying on the ground, low sun illuminating the ground, all quiet and calm.

A clear winter’s day:

You have to be standing all-but on the HBF to take this:

A selfie, of sorts: straight down landing on Stair Bridge:

I managed a couple of runs from near Rohallion Lodge up toward the A9 with the drone, spliced them together into a fly-by to give an impression of the topology.

And a still photo (I still shoot them! – but mostly HDR panoramas…) looking east from above the cusp of the saddle landform between old and new forests:

To wrap up the afternoon, there was some lovely light on an avenue of beech trees, walking back to the main road:

Bucket-list Item: CHECKED!

Strathearn Sunset

Posted on 2017-12-15 by spodzone

My sense of the geography of Strathearn has not really fitted together until quite recently. There have been a few locations, isolated points and a few lines: the A822 from Gilmerton up past Monzie to the Sma’ Glen; The Hosh at the foot to access Glen Turret; a small B-road between the two; a hill known as Kate McNiven’s Crag; and one or two other areas. More recently I’ve been climbing hills, “bagging” Torlum Hill and Laggan Hill as part of the Lady Mary’s Walk circuit out of Crieff.

The Highland Boundary Fault emerges in a burst of very lumpy landscape at the southern end of the Sma’ Glen. But what it does in the rest of Strathearn to the west, I’ve never really seen.

A couple of weekends ago I explored the Knock of Crieff independently; it struck me that the path up the north side afforded the perfect view along the length of the strath to the far mountains in the west, an elevated view along the glacial U-shape.

So late on Sunday afternoon I took the drone for a spin slightly out over the strath and made a panorama of 7 shots, each a 5-shot HDR exposure bracket sequence – blended on Linux, stitched and edited in Serif Affinity Photo for the iPad.

Lowlands to the left of me; Highlands to the right…

And just for the record, this is what it looked like in the middle of stitched the blended panorama, before I cropped and toned it:

Birnam Hill: Hunting the Highland Boundary Fault

Posted on 2017-05-13 by spodzone

I’ve been to Birnam Hill and Duncan’s Hill area at least six times, so it made a good testing ground for the new Pentax K-1 camera.

It wasn’t the best of days for landscape photography – a bit early in the day for what little light there was to be really photogenic – but there was a moment when the sun broke through and illuminated some birch trees on top of Duncan’s Hill most beautifully:

For some years I’ve known the Highland Boundary Fault crosses the A9 around Dunkeld/Birnam area, but never really pinpointed the exact location.

On my first visit I walked around Duncan’s Hill through Birnam Wood and Rochanroy Wood: I observed a particular lump of rock exhibiting clear strata sticking out of the hillside:

As I passed the edge of the established woodland, there was a pronounced drop of about a metre to the level of the new conifer trees to the right. And I wondered if this was a particular noted geological formation.

Three paths: this one leads down the line of the Highland Boundary Fault

On more recent visits I geotagged the location and compared with the British Geological Survey’s maps to see the rock types change either side of the dip – till, changing to slate and grit and then to psammite and semipelite typical of the Highlands.

On further investigation with Google Earth, the photo on the corner of the dip is right on the line of the Highland Boundary Fault itself, running up from Rohallion Loch through the lodge, round north-east turning easterly across the A9 south of Birnam.

My photo pinpointed right on top of the Highland Boundary Fault

Got it! Clear confirmation. Right on the money, first time 🙂

The path continues across a pronounced dip in the landscape before continuing up the other side to Stair Bridge Viewpoint and the King’s Seat on Birnam Hill.

Of course my favourite clear pure waterfall was still running:

The path affords some excellent views back of the Highland Boundary Fault cutting across the landscape:

And finally, as far up the hills as I wanted to go that day, at Stair Bridge Viewpoint I was rewarded with a clear landscape vista over Rohallion Lodge to the Lowlands to the south:

Landscape and Geology – an NC500 road-trip

Posted on 2017-03-17 by spodzone

Back last November I spent a very happy few days staying up North; the first day was spent in Glen Affric (sunrise, trees, water and light).

Photo Map – a long drive around Wester Ross

In the few years since I was last up there, there’s been a concerted push to market the road around the far north of Scotland as an “answer to Route 66” and thereby promote it as a tourist attraction.

The second day of my holiday saw lousy weather, completely overcast and foggy for much of the time. So I spent the day driving around Wester Ross wondering where the scenery had got to… trying not to think of it as the NC500 but actually enjoying several stops along the route that I’ve been to previously.

The first stop was the well-known view from a layby in Glen Dochart, above Kinlochewe to admire the sinuous road:

An obvious scene: the road wending through Glen Dochart toward Kinlochewe (not depicted: Kinlochewe, because of the mist).

Pity about the mist…

A little further along on the way through Kinlochewe are two mountains – Beinn Eighe to the left and Meallan Ghobhar and Coille na Dubh Chlaise to the right. We pulled off the A-road and Doglet had his breakfast more or less directly on the Loch Maree fault-line whilst admiring the quartzite rock strata.

There wasn’t much to be said for the views across Loch Maree, although the contrast of dull grey skies and warm autumnal orange and yellow colours was pleasant.

Some years ago, there was a TV documentary, a former politician’s search for the most natural woodland in the UK. After much searching around down south in the New Forest, he came north and explored Caledonian Forest remnants, finally finishing up on an island in Loch Maree – a rather bizarre arrangement of an island with a lochan with another island inside that – on which he stated the trees were least likely to have been touched by mankind. There is an obvious viewpoint, a small section of beach, at Slattadale toward the north-west end of Loch Maree, from which the group of islands can be seen.

Of all the photos I made during that day, this was perhaps the most classical landscape, in that I had the idea for these photos – the location, leading lines of foreground boulders, large expanse of silvery water and Slioch in the distance – planned in my mind for ages before revisiting the area.

What you don’t see is how, while I was making these photos (long exposures, totalling a minute’s exposure, focus-stacked) there was another photographer sitting 20yd away, cooking his morning breakfast – so the photos fail to include the clouds of fragrant bacon and fish smoke billowing past the camera…

Speaking of lunch, mine happened at Badachro, at the Inn. Highly recommended – everyone loved Doglet, which is a good start, and the burger was tasty as ever. Mostly the thing I like most is how the coastline is just like Plockton – west-coast rocky sea-lochs and seaweed – but without actually being Plockton that everyone else flocks to see.

And this is what it’s really like at Badachro:

On a previous trip I had explored as far as Poolewe but not had a chance to go further; this time I stopped off at Loch Tollaidh to admire the rocky outcrops across the water (Lewisian Gneiss and other igneous rock).

Classic Wester Ross landscape – huge lumps of Lewisian gneiss, beside Loch Tullie

Signs of industry: on the shore of Loch Tollaidh is a small jetty, presumably a put-in for boats to go inspect the small salmon farm. That and the remains of a very dead boat, wood bleached inland, caught my attention:

On travelling up the coast to Mellon Udrigle (what a wonderful name!) I was struck by the view across the Wester Ross Marine Protected Area to the mountains on the horizon on the mainland. On the left, a bit of misty cloud drapes over the top of Beinn Ghobhlach; to the right, there’s more mist flowing over Sail Mhor but the huge bulk of An Teallach was completely hidden behind the cloud.

A wide-angle panorama: low-lying cloud (with a bit of precipitation) and mist flowing over Sail Mhor – the full bulk of An Teallach is completely hidden in the cloud beyond.
The mountain on the far left is Beinn Ghobhlach.

By the time I got back onto main roads, with a very long drive ahead, the light was fading fast toward dusk and the blue hour and clouds in front were thick and closing in fast, so I made one final photo for the day by the side of Little Loch Broom and scarpered fast.

Lots of mist in the distance, travelling the A832 past Beinn Ghobhlach.
I was rather glad to get back in the car and head off before the weather got really bad!

Around Glen Affric: water

Posted on 2017-01-19 by spodzone

I had a short holiday at the start of last November, a few days spent in Glen Affric. There are several aspects why it’s my favourite part of the planet, but for the purposes of this post, we consider the role of water in shaping a landscape, eroding its way through rocks to form river, gorges and waterfalls.

First, the impressive 150-foot drop of Plodda Falls from the top:

Second, some of the cascades in the River Affric, part of the way around the River Walk, rich autumn colours glowing in the morning sunlight:

And finally, a couple of 360-degree panoramas, partly to offer a behind-the-scenes view – they take a little while to download once clicked:

Falls of Bruar Revisited

Posted on 2016-06-30 by spodzone

With a couple of hours to spare on Sunday afternoon, I revisited the Falls of Bruar. Even on a grotty wet day there were plenty of opportunities, around the lower bridge.

It’s at least the 8th time I’ve been there – but the geology is impressive as always with the natural arch formed by the river eroding the local rock (mostly psammite, as with much of the Highlands).

Some experiments with Live Composite mode on the Olympus Pen-F, as well as the usual (for me) high-resolution mode; everything taken using a circular polariser and ND4 filter for longer exposure times. Having made initial RAW conversions using RawTherapee, everything has been passed through LuminanceHDR to even-out the white-balance and tonemap for better image tone. (In cases where there’s only a small area of light in the frame, such as these flowing waterfalls, the Pattanaik algorithm can give interesting high-contrast results – set the gamma to about 0.3 and the frame turns mostly black with just the highlights remaining.)
