Description :
Terracettes and turf-banked terraces exist at Tiffindell Ski Resort in the Drakensberg of the Eastern Cape at altitudes between 2750 m and 2880 m on slopes of between 15° and 26°. The terraces move downslope under the influence of gelifluction, which is essentially a combination of frost creep and solifluction. Both terraces and terracettes are part of the periglacial environment and are active under present climatic conditions. - (AJC)
