50 km east of the city of Khorixas in northwestern Namibia.
This rock formation is an erosion residue, a kind of mini-witness mountain of a layer level that extends further east parallel to and north of the Ugab.
This layer level, like the rock finger, consists of deposits from the Tertiary forerunners of the Ugab river system and tower over the recent valley of the Ugab by up to 160 meters.
These deposits are predominantly carbonated sandstones and conglomerates.
In addition to the rock finger, there are some other, in some cases much larger, erosion residues in this area - “real” witness mountains in the form of table mountains.
