Abstract
ABSTRACT Landforms most easily explained by recourse to nivation processes have been reported from the eastern Orange Free State and adjacent Lesotho. These landforms are usually associated with south-facing slopes above 1800 m altitude. A pair of landforms on a north-facing slope occur between 2100 and 2300 m. These are attributed to nivation action. The features consist of three ridges transverse to the slope whose components have undergone considerable disintegration in situ and rearrangement downslope. Blocks are absent from the upper third of the slope. The feature is attributed to frost shattering from a cliff, transport across a snow patch and accumulation as a series of three protalus ramparts. Nivation activity was therefore not confined to south-facing slopes.
