Amazonis Planitia is one of the smoothest plains on Mars. It is located between the Tharsis and Elysium volcanic provinces to the west of Olympus Mons in the Valles Marineris region of the Memnonia quadrangle, centered at 24°48′N 196°00′E / 24.8°N 196.0°E. Its topography exhibits extremely smooth features at several different lengths of scale. Its name derives from one of the classical albedo features observed by early astronomers, which was in turn named after the Amazons, a mythical race of warrior women.
