A rock dubbed "Uchben" in the Columbia Hills inside Gusev Crater is seen in this photo taken by the Mars Rover Spirit and released Nov. 4, 2004. Spirit, having trekked nearly two miles across the flat terrain of the vast Gusev Crater region where it set down, was zig-zagging up the rugged Columbia Hills and was nearly 200 feet above the surrounding plain.
