Dark, wind-blown deposits and landslides on Mars
Dark, wind-blown deposits and landslides on Mars
This 25-kilometre-wide impact crater shows striking signs of erosion. Unstable rock formations have repeatedly slid down from its 1500-metre-high crater rim, pushing into the bowl-shaped depression and filling it with rocky debris. At the rear of the crater rim, the wind has deposited dark sands as the topographical 'obstacle' acted like a sediment trap, causing most of the transported material to accumulate there.
