Mars Exploration Rover Spirit is climbing into the Columbia Hills and up the slope of “Husband Hill”. Spirit has also discovered possible evidence for water in the region during the distant past, though the water was likely not as extensive as it was on Meridiani Planum. The Columbia Hills and surrounding terrain all sit within Gusev Crater.
