Umm al Binni lake
Based on the interpretation of satellite imagery, Sharad Master suggests the 3.4 km (2.1 mi) in diameter dry lake may be an impact crater based on its nearly circular, slightly polygonal rim shape, and contrasting shape to other lakes in the region. However, the circularity of its shape has been disputed, with a 2018 study finding that the northeastern and southwestern sections of the lake rim were straight, corresponding to the directions of regional faulting. As to its origin, Masters rejects karst topography, salt doming, tectonic deformation, and igneous intrusion as well as possible bombing or man-made origins. However, a 2018 study concluded that the formation of the lake could be better explained by the subsidence of the underlying basement fault blocks, and that the southern part of the rim had been anthropogenically shaped.

It was climbed in November 2004 by English explorer Ginge Fullen, who recorded a GPS reading of 3,628 meters at the coordinates in the adjacent table. The location is consistent with SRTM and Russian topographic mapping, although these sources are more consistent with the CIA height.
