Matjiesfontein surrounding Karoo region is a flat, sparsely populated semi-desert.

Matjiesfontein Matjiesfontein is a settlement in Central Karoo District Municipality in the Western Cape province of South Africa.

Following the arrival of the early European colonists, the area was settled by Afrikaaner Trekboers and Griqua people. The town itself owes its existence to the Cape Government Railways, and to the route that their founder, Cape
Karoo (crater) of its craters exceeds the critical crater diameter. This would explain the crowding of giant craters, since none of these would result in global degradation. Indeed, if Karoo, at 33 km diameter, represents D and resurfaced the asteroid, then the 5 or more other giant impacts must have happened subsequently, which is highly unusual given that they are in fact almost just as large. Thus α = 1.33 from Fig. 2a is likely a lower limit on Mathilde’s attenuation. Karoo (crater) Karoo is an impact crater on the Asteroid 253 Mathilde, named for the Great Karoo Basin, a coal basin
