Twin Peaks are moderate size hills to the southwest of Mars Pathfinder landing site. They were discovered on the first panoramas taken by the Imaging camera on July 4th, 1997. They were subsequently identified in Viking Orbiter images taken over twenty years earlier! The peaks are about 30-35 meters (about 100 feet) tall. North Twin is about 860 meters (2800 feet) from the lander and South Twin is about a kilometer (3300 feet) distant. Bouldery ridges and swales, or hummocks of flood debris can be seen in the image. The debris ranges from a few tens of meters away from the lander to a kilometer. The large rock at the right edge of the scene is nicknamed 'Hippo'. This rock is about a meter (3 feet) across and 25 meters (80 feet) distant.
