Karoo (crater) Karoo (crater) Karoo is an impact crater on the Asteroid 253 Mathilde, named for the Great Karoo Basin, a coal basin in South Africa. It is 33.4 kilometers in diameter and was the most prominent crater seen during NEAR Shoemaker's Flyby of the Asteroid. The critical crater diameter is the scale at which cratering “goes global” and results in a solitary distinct crater. All smaller craters—however large D might be—are local events. Mathilde is thus a particularly interesting case, since it is the largest asteroid imaged at sufficient resolution to show that its topography is clearly exogenic, governed by impacts.
Gibson Desert severe drought which had dried up all of the springs and depleted the bush foods, a group of the Pintupi people who were living a traditional semi-nomadic desert-dwelling life, walked out of a remote wilderness in the central-eastern portion of the Gibson Desert (northeast of Warburton) and made contact for the first time with Australian society. They are believed to have been perhaps the last uncontacted tribe in Australia. On the eastern margin of the region, population centres (which include people of European descent) include Warburton, Mantamaru and Warakurna. Young Indigenous adults from the Gibson Desert region work in the
