Spallanzani's Neighbor

Along the southeast rim of the Hellas Basin, a 27 km diameter crater hosts an eroded layered deposit like many of the neighboring craters. Compared to the weirdly-shaped remnants of the deposit in the adjacent Spallanzani Crater, the layers in this image are more subdued. It is not clear why material deposited into and eroded from two craters so close together would appear so different.
