Abstract

This study applies a combination of geomorphological and macro- and micro-scale sedimentological techniques as research tools to determine the process origins of deposits along the Sekhokong south-facing slopes. It is suggested that the the south-facing slopes were dominated by glacial processes during the Last Glacial Maximum (LGM), as is evident from the moraines, while the proposition for previously described north-facing glacial cirques is rejected based on the absence of erosional/depositional evidence and greater insolation received on these warmer equator-facing slopes. Rather, they propose that the observed north-facing hollows are a product of a multitude of geomorphic processes spanning several tens to hundreds of thousands of years
