The Crazy Floor of Hellas Basin

The deep floor of Hellas impact basin is often obscured by haze, but at times we get some clear views. There are some strange landforms down there, and this image is one example.

The image covers the rim region of a crater that appears filled in, perhaps by river sediment (the rim is breached by a channel). The colors (see enhanced color subimage) indicate that diverse minerals are present.
