| Description: | South-west of Marble Lodge, Glen Tilt, 6.4 km. north of Blair Atholl, Perthshire. Gully erosion in a glacial moraine barrier. Glacial moraine deposits form a barrier across the Tilt Valley and have subsequently been cut through by a stream which has also been partially deflected by it. Mountain stream channels are eroding through the drift to form steep V-shaped gullies the sides of which are sometimes bare where there is active erosion. Note the centre stream cutting back up the centre of a spur, and the spur to the left which has just been breached from either side. Rapid erosion on the now un-vegetated breach will, in time, cause the top and the bottom of the spur to become separated. |
