Basalt columns in a (left) fresh crater near Marte Vallis on Mars look remarkably similar to columns at the Clarkston outcrop (right) in Washington state. The Mars columns were imaged with the HiRISE camera on NASA's Mars Reconnaissance Orbiter. The aerial view of the Clarkston outcrop was taken from a remote-controlled plane. The scale (yellow bar) of both images is 10 meters (about 33 feet). Credit: NASA/JPL/University of Arizona and Goddard/David Weiss
