This recent Mars Global Surveyor Mars Orbiter Camera image shows mesas and smaller buttes that occur on the Elysium Plains, approximately 185 miles south of the Cerberus region in the Martian eastern hemisphere. Like the world-famous Monument Valley located in the Navajo Nation on the border of Arizona and Utah, this “Martian Monument Valley” consists of a series of mesas and buttes that have formed by erosion of layered bedrock.
