Photo: Twin Peaks are small hills located southwest of the Mars Pathfinder landing site in Ares Vallis, the Chryse Planitia region. They were discovered on the first panoramas taken by the IMP camera on July 4, 1997, already identified on images taken by Viking Orbiter. The peaks are 30-35 meters (-100 feet) high. North Twin is about 860 meters (2800 feet) from the lander and South Twin is about one kilometre away (3300 feet). The scene includes mounds of rocks and gullies of flood debris located a few dozen meters from the lander to South Twin. These Twin Peaks are named after a couple of hills in San Francisco, California. They do not seem to have a Latin equivalent given by the IAU. Credit: NASA/JPL-Caltech/MSSS.
