Acidalia Planitia

planitia on Mars

Acidalia Planitia is a plain on Mars. It is located between the Tharsis volcanic province and Arabia Terra to the north of Valles Marineris, centered at 49.8°N 339.3°E / 49.8; 339.3. Most of this region is found in the Mare Acidalium quadrangle, but a small part is in the Ismenius Lacus quadrangle. The plain contains the famous Cydonia region at the contact with the heavily cratered highland terrain. The plain is named after a corresponding albedo feature on a map by Giovanni Schiaparelli, which was in turn named after the mythological fountain of Acidalia. Some places in Acidalia Planitia show cones; some researchers have suggested that these are mud volcanoes. The scientific community is still debating the possible existence of an ancient ocean over Acidalia Planitia and other parts of the northern lowlands.
