17: Devils Staircase to Kinlochleven

The view looking east from the top of the Devil’s staircase is a vast panorama of mountains and valley.   I did say that from this point is might be possible to gather a better picture of the caldera and maybe, if you have a working knowledge of geology, it is possible to pick out the tell-tale features of a collapsed volcanic ring. However I can only take my hat off to the Victorian pioneers who came to this conclusion, when it would have been a lot easier to explain the whole process at some other site that hadn’t experienced further volcanic activity and then had glaciers crashing through the entire landscape, thereby obscuring the original structures.   Although this is the point where the original fracture occurred that caused the volcano, this is no longer the centre of the caldera, we are in fact on the northern edge. Looking east, the glacier crashed through the walls, flattening the caldera.  It rises up above the Glencoe mountain resort and then heads to Stob Dubh to the sou

16: The Devil's Staircase (Glencoe mountain resort to the Devil's Staircase)

The geology of Glencoe is so complex and varied that I almost dare not speak of it. It is famous for being the first recognised caldera volcano and my first thought on looking around was how? It is not obvious to the lay person that this landscape is a collapsed cauldron and the geological events that have occurred since, such as the movement of the land from the southern hemisphere to the north and the numerous collisions with continents that happened along the way, have deformed the circle and made it a mangled ellipse. The subsequent ice ages have sliced a deep valley through the caldera walls, further obscuring the landscape. The Glencoe mountain resort on the very eastern edge of the caldera, is maybe not the best place to appreciate the geology. On today’s route the West Highland Way heads down the glen, following the scrape of the glacier on its slide to the sea, until the route turns to climb the Devil’s Staircase. However the top of the Devil’s Staircase lies under the peak of

10: Here be bears (Inversnaid to Inverarnan)

To quote Stephenson and Gould in British regional geology: the Grampian Highlands, fourth edition, 2007 when discussing the features you might expect to see in this part of Scotland,  'Metagreywackes, siliceous psammites and fine-grained quartzites are interbedded with the predominant well-foliated green schists containing abundant chlorite, epidote, biotite and albite porphyroblasts.' Well, quite, I couldn't have put it better myself.  When I was young we lived in London and I would often head in the school holidays to the museums in South Kensington. The big draw these days is the Natural History museum but back then dinosaurs weren't quite as popular as they are today and much of the ground floor was a series of somewhat lacklustre dioramas that were populated with a cast of vaguely unsettling stuffed animals.   Around the corner in Exhibition Road was the Science museum which became a big favourite with me mainly due to the number of interactive displays. The joy

7: Sunshine on Scotland (Drymen to Conic Hill)

The Way doesn’t actually enter Drymen, it skirts around the eastern edge before turning and heading off to the north.  As we left the village ahead of us i n the dazzling sunshine we could make out the outline of a lone hiker tottering under the weight of her backpack, occasionally stopping to rearrange her load. We quickly caught up with our photographer from yesterday morning, who although cheerful, seemed to us to be finding her load a heavy one. To my eye she had a sixty-five litre pack that was ready to burst. She told us she hadn’t just come to walk the Way but spend about a month exploring the UK and our impression was that she had brought all of her supplies with her. We quickly outpaced her, indeed we were outpacing most of the other hikers that we met on these early stages.   During our preparation for the walk, as we don’t have anything that could realistically be called a hill in Essex, Chris had slowly but surely upped the speed that we walk at. We did the same before walk

2: Why walk the West Highland Way?

Scotland’s first long distance path is one of the most popular long-distance walks in the world. So what draws over 30,000 people each year to walk the West Highland Way?   Is it the spectacular scenery? - which is practically continuous from the start at Milngavie, a suburb to the north of Glasgow to the end at Fort William, nestling under the shadow of Ben Nevis the highest mountain in the British Isles.    Glencoe Or is it history? From the Romans who built the Antonine Wall, part of which can be traced through Milngavie. Or passing by a neolithic monument of standing stones at Drumgoyach? - the significance of which is lost in time. Or walking in the steps of Rob Roy and Robert the Bruce? Or crossing Glencoe? - the setting for the vicious slaughter of members of the clan MacDonald. Maybe looking across to Lochan Lunn Da Bhra? -  where on a tiny island Macbeth was alleged to reside (a Scottish King who should be contacting his lawyers about the lack of historical accuracy in the Sha
