| Caption: | Oblique aerial view of Loch Avon from the east, Aberdeenshire. |
| Description: | Loch Avon at the heart of the Cairngorms occupies the floor of a typical parabolic glaciated valley cut into the granite plateau. The valley is one of the three largest troughs in the area, the other two being Glen Geusachan and Glen Einich. It is thought these main glacial troughs were cut beneath an ice sheet crossing the mountains from the south-west and not at the time when the Cairngorms had individual corrie glaciers. The evidence is twofold, the convex valley heads that could only have formed by ice crossing them from the plateau above and none of the troughs originates from a corrie which could have acted as source areas for the glaciers that cut the troughs themselves. The surface of the loch at 730 m. O.D. is around 400 m. below the level of the plateau. Loch Etchachan, situated some 200 m. above and to the south of Loch Avon is a fine example of a flooded high-level corrie. Flooded glacial trough and high-level corrie lochan. View south-westwards from upper Glen Avon towards the mesa summit of Cairn Toul with the rocky faces of Braeriach to the right and the rounded summit of Ben Macdui to the left. |
