Gordii Dorsum

This VIS image of the northwestern end of Gordii Dorsum shows where the dorsum meets Amazonis Planitia. This area of Mars is dominated by poorly cemented surface material that is easily eroded by the wind. Features align with wind direction, indicating that the winds in this region blew to the northwest. Gordii Dorsum is part of the larger Medusa Fossae Formation of wind eroded materials south and southwest of Olympus Mons. The nature of the material being eroded is not known, but may be ash fall from the large volcanoes in the region.
