At Corrie and the Cock of Arran they rest on Upper Carboniferous strata; in Ben Lister Glen, on the lower limestone group of the Carboniferous Limestone series; and on the west coast they repose on the Old Red Sandstone.
To the north lies the village of Corrie which takes its name from a rugged hollow in the hill of Am Binnein (2172 ft.)which overshadows it.
From the head of Glen Derry, with its blasted trees, the picture of desolation, it becomes more toilsome, but is partly repaid by the view of the remarkable columnar cliffs of Corrie Etchachan.
Usually the upper part of a corrie is formed by a crescent of naked rock, from which long trails of debris descend to the bottom of the hollow.
From Corrie they can be traced southwards and inland to near the head of Ben Lister Glen.
The small development of Upper Carboniferous strata, visible on the shore south of Corrie and in Ben Lister Glen, consists of sandstones, red and mottled clays and purple shales, which yield plantremains of Upper Carboniferous facies.

The lowest group is on the horizon of the Calciferous Sandstone series, being visible at Corrie where it underlies the Corrie limestone, and is traceable southwards beyond Brodick.
