This unnamed crater in Utopia Planitia has plenty of interesting formations to study: scalloped depressions, concentric crater fill, and alcoves that might be associated with gullies.
These features were also spotted in a Context Camera (CTX) image, so another of our goals is to get a better look at any stratigraphic relationships, especially to find evidence if those gullies are related to the alcoves that are visible at CTX resolution. The crater just about fills the width of our HiRISE image, so it’s 5 kilometers across.
