Caption: The north-west face (868.38 m.) of Aonach Dubh, from near Clachaig, Glen Coe. Argyllshire.
Description: Lower Old Red Sandstone volcanic rocks. The rocks are preserved in a downfaulted block within an elliptical ring structure called a cauldron subsidence. A glacial moraine mound is in the foreground. The topmost scree-clad slope on right, consists of hornblende-andesite and agglomerate, which overlie thick flows of rhyolitic lavas and ignimbrites forming the upper part of the bluff. These overlie numerous flows of augite-andesite, which rest unconformably on phyllites. The hill slope on right consists of granite, 'Fault Intrusion', intruded into Highland schists (quartzite, etc.). These rocks are part of the Glencoe Cauldron Subsidence, an area 9 miles by 5 miles that has undergone downfaulting within a ring-shaped fault, with several thousands of feet downthrow.
