-17.388956, 30.048882
Location: 
Angwa River, on the road between Chinhoyi Caves and Alaska Mine.
Stratigraphy: 
Deweras Group
Description: 

Large-scale  planar  crossbedded  arkosic  sandstones of  the Deweras Group  display small-scale features that are diagnostic of aeolianites, including em-scale inversely-graded ripple-cross-laminated "subcritically-climbing translatent strata" (Hunter,  1976),  wedge-shaped  massive grainflows (avalanche  deposits),  and  pinstripe lamination. These are among the oldest authenticated aeolianites in the world (Master, 1995).
