Layered Bedrock
This un-named crater in southwestern Arabia Terra contains a treasure!
Layered sediments are the key to the puzzle of Martian history. They tell us about the conditions that existed when the sediments were deposited, and how they changed over time.
A Tale of Collapse Terrain
North of Ganges Chasma lies Orson Welles Crater, whose floor contains broken up blocks we call chaotic terrain and which is the source for the major outflow channel Shalbatana Vallis.
