Wonderland of the Mawrth Vallis Region
ESP_072610_2030  Science Theme: Sedimentary/Layering Processes
The Mawrth Vallis region of Mars reveals some of the most colorful layered sedimentary rocks on Mars. There are ongoing debates about how these clay-rich deposits formed on very ancient Mars, more than 3 billion years ago.

Mawrth Vallis has often been on the candidate list for possible landing sites for robotic exploration. Located between the southern highlands and northern lowlands, the valley is a channel formed by massive flooding which occurred in Mars’ ancient past.
