This image covers Luki Crater in the Southern highlands. This crater formed on the floor of Uzboi Vallis between Hale and Holden craters, near the confluence with Nanedi Vallis.
The central region of the crater consists of uplifted ancient bedrock with a great variety of rock types, as shown by the color diversity.
