It lies about one crater diameter to the northwest of Cockroft, and due west of Evershed. This crater has been worn by impact erosion, leaving the features rounded and somewhat irregular. But the perimeter of the rim can still be traced in the rugged surrounding terrain. There is a small, fresh crater laid across the eastern rim, and some old and worn depression along the southern and western inner wall. On the whole, there is little to distinguish this crater from the multitude of other impacts in this region.
