Protalus ramparts and the altitude of the local equilibrium line during the last glacial stage in Bokspruit, East Cape Drakensberg, South Africa

Cape Province ; Glacial features ; Grain size distribution ; Moraine ; Palaeoclimatology ; Permafrost ; Quaternary ; Residual landform ; Sedimentology ; South Africa
A ridge of unconsolidated debris at an altitude of 2000 m, located beneath cliffs in the East Cape Drakensberg of South Africa, is interpreted on morphological and sedimentological evidence as a protalus rampart. The rampart is believed to have

The age of alluvial fan deposition at a site in the southern uplands of Scotland

The age of a large alluvial fan debouching onto the valley floor of the River Tweed, in southern Scotland, and the sequence of events relating to this, are investigated using geomorphological, sedimentological, palynological, archaeological
