| While Meall a'Ghiubhais is a straightforward climb from the path, the steep screes and formidable northern crags of Ruadh-stac Beag makes a direct ascent almost impossible. |
| We conclude that the Sgurr Beag Thrust, a major tectonic break separating the Morar and Glenfinnan groups of the Moine, is mainly of Neoproterozoic, not Caledonian, age. |
| We followed a faint path south, passing a small loch below Sidhean Beag where bonxies were creating turmoil amongst the oystercatcher nests. |
| Southwest of the Dornoch Firth, the Sgurr Beag Thrust divides the Moine rocks into two major nappes. |
| Walks up Munros, such as Schiehallion, Buachaille Etive Beag or Ben Lomond, fall into this category. |
| The two rift sequences were subsequently juxtaposed by displacement on the Sgurr Beag thrust and interfolded during the Caledonian orogeny. |
