Present‐day periglacial activity in the Natal Drakensberg, Southern Africa: A Short Review
Abstract Active periglacial features are described for the Natal Drakensberg, a mountain region in southern Africa reaching up to 3482 m a.s.l. Surficial diurnal freezing is evident by features associated with needle ice activity, while thufa and micropatterned ground indicate more severe frost pene...
