OBSERVATIONS ON THE FISH RIVER CANYON IN SOUTH WEST AFRICA

Abstract

The Geology and Geomorphology of the Fish River Canyon, as investigated during a reconnaissance expedition in January 1956, are briefy described, and certain evidence is put forward in support of the proposition that, despite previous assertions to the contrary by other authors, the double canyon consists of an erosional lower component carved by rejuvenation into the floor of the structural trough which forms the upper canyon. In so far as limited observations permit, certain tentative inferences are also drawn regarding the history of the canyon, as a basis for future, more detailed, investigation.
