This VIS shows part of Acheron Fossae. Acheron Fossae is the highly fractured, faulted and deformed terrain located 1,050 kilometers (650 miles) north of the large shield volcano Olympus Mons. Lava flows from Olympus Mons at the base of Acheron Fossae show that the fossae predate the flows. The scarps visible in this image are approximately one kilometer (3,300 feet) high.
