- Description: Certain debris accumulations in Bottelnek are ascribed a rock glacier origin on the basis of morphological and sedimentological evidence. Radiocarbon dating indicates that rock glaciers were active at or subsequent to 21 000 BP and that cold, stadial conditions, existed on the region after 27 000 BP and before 13 000 BP, during the Bottelnek Stadial. At least sporadic permafrost existed in Bottelnek when the rock glaciers were active.

- Description: The paper presents the results of preliminary investigations at Birnam, in the Rhodes area of the eastern Cape Drakensberg, which may have important implications for palaeoenvironmental reconstructions in Southern Africa. A study has been undertaken on a sedimentary sequence exposed by fluvial incision on the outer bend of the River Bokspruit, at an altitude of 1850 m.
