This crater floor has a hummocky texture (“brain-coral”-like), and curved structures, possibly from glacial-like flow.
What’s of note is how HiRISE plans certain observations–like this one–where anywhere in the area is likely to be interesting enough for an image. This is unlike other observations where the planning needs a precisely-targeted area to capture a specific feature of interest. We call this an “NIO,” or non-interactive observation.
