Pothole erosion of a dissected Lake‐shore platform in Peat, Loch More, Halkirk, Caithness

Abstract

An unusual combination of environmental factors has brought about the excavation of a series of classical cauldron‐shaped potholes in a dissected lake‐shore platform of peat on the shore of Loch More, Halkirk, Caithness. The potholes have both been eroded by, and now contain, ‘cobbles’ of peat. Some potholes are obviously currently active during periods of heavy rain, while others are abandoned or at least less active, being filled with a growing layer of grass. The platform has been deeply dissected by water erosion along contraction joints which formed as the peat dried out ('nagging') and it now generally resembles a karst‐like miniature ‘bad‐lands’ topography with small ‘mesas’ and ‘buttes’.
