Broad lava plain in the southern highlands of the planet Mars
Hesperia Planum
MOLA colorized relief map of Hesperia Planum region. Hesperia Planum has fewer impact craters than the surrounding Noachian highlands of Tyrrhena Terra and Terra Cimmeria. This indicates that the plain is younger than its more heavily cratered surroundings.
Hesperia Planum is a broad lava plain in the southern highlands of the planet Mars. The plain is notable for its moderate number of impact craters and abundant wrinkle ridges. It is also the location of the ancient volcano Tyrrhena Mons (Tyrrhena Patera). The Hesperian time period on Mars is named after Hesperia Planum.[2][3]
