another long winter: Surface of Mars, photographed by Mars Reconnaissance Orbiter, 8th October 2008.
Around 2°S 206°E, “Arcuate ridges in the Medusae Fossae Formation”.
The Medusae Fossae Formation is an area of easily-eroded terrain covering 2,000,000 square kilometers (about the size of Mexico, or Greenland). The MFF shows a range of aeolian (wind-formed) features like dunes and yardangs. The origin of the MFF is uncertain, but may be a giant ash deposit from one or more of the surrounding volcanoes (Elysium, Apollinaris, Olympus, Ascraeus, Pavonis, and Arsia Mons).
