Flat-topped hills (called Karoo Koppies) are highly characteristic of the southern and southwestern Karoo landscape. Karoo Koppies hills are capped by hard, erosion-resistant dolerite sills. This is solidified lava that was forced under high pressure between the horizontal strata of the sedimentary rocks that make up most of the Karoo's geology ...
First opened to the public in October, 2005, Government Canyon State Natural Area (GCSNA) preserves 12,244 acres (49.5 km 2; 19.1 sq mi) of rugged hills and canyons typical of the Texas Hill Country.

The two areas consist of semi-arid to arid tracts of the Upper Karoo (to the south) and the Southern Kalahari (to the north). Both areas are rich in archaeological traces inter alia of the Later Stone Age, while rocky hills and outcrops in the southern area (which has been referred to as ǀXam-ka ǃxau, meaning home of the ǀXam) have a wealth of rock art sites, preponderantly in the form of ...
The Ecca Group is represented by the orange key on the map. The Ecca Group is the second of the main subdivisions of the Karoo Supergroup of geological strata in southern Africa . It mainly follows conformably after the Dwyka Group in some sections, but in some localities overlying unconformably over much older basement rocks.
