Gearr Aonach & Aonach Dubh,Glen Coe 20th April 2017

Glen Coe (Scottish Gaelic: Gleann Comhann,pronounced [klan̪ˠˈkʰo.ən̪ˠ]) is a glen of volcanic origins, in the Highlands of Scotland. It lies in the north of Argyll, close to the border with Lochaber. It is often considered one of the most spectacular and beautiful places in Scotland, and is a part of the designated National Scenic Area of Ben Nevis and Glen Coe. The narrow glen shows a grim grandeur. The glen, approaching from the east on the main A82 road, is surrounded by wild and precipitous mountains. Further west at Invercoe, the landscape has a softer beauty before the main entrance to the glen. The main settlement is the nearby village of Glencoe located at the foot of the glen. near the site of the 1692 Massacre of Glencoe.

The Glen is named after the River Coe which runs through it. The name of the river is believed to predate the Gaelic language, and its meaning is not known. It is possible that the name stems from an individual personal name, Comhan (genitive Comhain).

The glen is U-shaped, formed by an ice age glacier, about 16 km (9.9 mi) long with the floor of the glen being less than 700 m (0.4 miles) wide, narrowing sharply at the Pass of Glen Coe about halfway along.

The entrance to the glen from above is on Rannoch Moor to the east, below the mountain of Meall a' Bhuiridh; Glen Etive runs to the south from nearby. The entrance to Glen Coe is marked by Buachaille Etive Mor, "the great herdsman of Etive" at the 'junction' with Glen Etive. Glen Coe then runs roughly west for about 12 km (7.5 mi) before turning north-west towards Loch Leven.

The south side of the glen is marked by a succession of distinct peaks: Buachaille Etive Mòr is followed to the west by Buachaille Etive Beag, then by the Three Sisters, shoulders of the Bidean nam Bian massif, subdivided by Coire Gabhail (the Glen of Capture or Lost Valley) and Coire nan Lochan. The third sister, Aonach Dubh, marks the western end of the glen. By contrast the north side of the glen is a stark wall of mountain, the Aonach Eagach ridge. The Ridge is crossed at the eastern end by the Devil's Staircase, an old military road opposite Buachaille Etive Mòr. To the north of Buachaille Etive Mòr, there is Beinn a'Chrulaiste. The western end terminates with the conical Pap of Glencoe (Sgùrr na Cìche), above Glencoe village, at the point where the glen opens out to Loch Leven.

The River Coe itself — Ossian's "dark Cona" — rises at the north-eastern base of Buachaille Etive Beag and flows west along the glen, with dramatic waterfalls at the Pass of Glen Coe. It then runs through the small Loch Achtriochtan before it turns north west. It then passes through Glencoe village, shortly before flowing into the sea loch of Loch Leven (a salt-water arm of Loch Linnhe) at Invercoe. Loch Achtriochtan is Loch Trychardan (three friends or relatives) in Timothy Pont's map of the area. In the glen to the east of Buachaille Etive Beag, the River Coupall runs north to the head of the glen, but it swings east round the Buachaille Etive Mòr to join the River Etive running south.

Geologically speaking, Glen Coe is the remains of an ancient supervolcano.It is considered to be one of the best examples of subsidence calderas. The eruption happened about 420 million years ago during the Silurian period, and the volcano has long since become extinct.

The landscape was further shaped by the processes of glaciation during the last ice age, 10,000 years ago.

Glen Coe was once part of the lands of Clan Donald, though since the ending of the clan structure they have progressively sold off their estates.

The land was purchased by the National Trust for Scotland in the 1930s using money donated by the Scottish Mountaineering Club. It was later found out that most of the money came from the SMC's then chair, Percy Unna. He laid out a number of conditions, known as the "Unna Principles" regarding how the NTS should manage the estate with regards to Access and maintaining the wild nature of the land. The building of a visitor centre caused some controversy, as some felt this to be a contravention of Unna's "Principles". The original centre was later closed, and a new one built further west, down the glen on land not part of the original purchase.

The last area of Glen Coe to be owned by the MacDonalds was the area around Invercoe. In 1894 Donald Alexander Smith, 1st Baron Strathcona and Mount Royal purchased this area and built a stately mansion, Mount Royal. In 2002 Alistair MacDonald of Glencoe made a successful eleventh-hour bid, and purchased the remaining lands of Lord Strathcona from his descendants. Alistair received unsecured loans from just six donors, and immediately set up the Glencoe Heritage Trust, a non-profit-making charitable trust, to secure the heritage of Glen Coe.

Most of the Glen is now owned by the National Trust for Scotland whose visitor centre has displays about both the natural and historical significance of the glen. Lord Maurice Hurrell F.C.I.I, was a certified [part] owner from December 2012 and also part owner of the land around Dunans Castle, Glendaruel, Argyll and Bute.
