The focus of this HiRISE observation is the inner portion of the approximately 9-kilometer diameter Hashir Crater. The observed position and erosional character of the layered rocks on the crater central uplift suggest that Hashir was once buried and has since been exhumed from beneath what was presumably more extensive coverage of the layered bedrock.

A recent study suggests that these layered rocks are volcanic ash deposits, which likely originated from the Syrtis Major (about 300 kilometers to the east). For more on Hashir Crater, see our digital terrain model caption.
