Layered Rocks near Mawrth Vallis

Mawrth Vallis is one of the oldest valleys on Mars, formed in and subsequently covered by layered rocks, from beneath which it is now being exhumed.

Mawrth Vallis is one of the oldest valleys on Mars, formed in and subsequently covered by layered rocks, from beneath which it is now being exhumed. The rocks surrounding the valley have been observed by the Omega spectrometer aboard the Mars Express spacecraft to include minerals with water bound within their structure. Thus, the Mawrth Vallis region is one of keen interest to the MRO CRISM team, which requested the above image (centered near 25.6°N, 19.4°W).
