This double-sided, full-relief map covers, at a scale of 1:200 000, the eastern Cederberg mountain range in the west and the Roggeveld escarpment to the east.
In between lies the entire Tankwa-Karoo and the smaller but drier Ceres-Karoo.
From Calvinia in the north the map stretches southwards to Middelpos, Sutherland and Laingsburg, and westwards to Touws River and Ceres, with Op-die-Berg and Wupperthal on the western edge.
