Holden Crater

(a) Layering in ancient lake sediments on the floor of Holden Crater. The layers are thin and continuous over distances of up to kilometers, consistent with emplacement in standing water. (b) Large bed forms were deposited where alluvium was washed into the crater as water impounded in Uzboi Vallis breached Holden's rim. Both images are subsets of MOC image M0302733, centered at 27.1° S, 34.9°W and 2.8 m/pixel resolution.
