The Eumenides Dorsum (Greek: back of the furies) is a mountain ridge, which was probably formed by volcanic activity and runs in a north-south direction, in the Medusae Fossae region of the planet Mars, which is covered by volcanic ash . The area is in the west of the volcanic Tharsis region .
Eumenides Dorsum is characterized by kilometer-long linear structures that are interrupted by channels, so-called yardangs (wind humps or sand walls). They are the result of wind erosion . In the south, Eumenides Dorsum has curved ridges, the origin of which is still unclear.
The area has about five times the area of the Saarland and extends over a length of 569.26 kilometers in the range 9.58 ° -0.01 ° north latitude and 155.06 ° south latitude and between 155.06 ° and 158, 46 ° west longitude.
The International Astronomical Union (IAU) named Eumenides Dorsum in 1976 after the goddesses of revenge in Greek mythology, the Eumenids .
On December 26, 2007, the High Resolution Stereo Camera (HRSC) of the Mars Express (MEX) spacecraft mapped the area with a resolution of 13 meters per pixel from a height of around 260 kilometers (orbit 5114).
