The Advanced Land Imager (ALI) on NASA's Earth Observing-1 (EO-1) satellite acquired this true-colour image on August 28, 2009. Sunlight shines from the southeast, leaving the northern and western slopes in shadow. The crater's rim rises some 20 to 30 meters above the crater bottom. The crater occurs on a block of Proterzoic rock more than 600 million years old, but the crater's age - which may be considerably younger - has not yet been identified.
