Exposures of Layered Rocks in the Argyre Region

May 7, 2011
This observation shows great exposures of layered rocks in Argyre region. Could it be evidence for an ancient sea or lake?

The Argyre region, also known as the Agyre quadrangle by the USGS, is also home of the Argyre impact basin, which contains some ancient eroded terrains, as well as other impact craters that HiRISE has imaged.

This caption is based on the original science rationale.
