Yardangs in Medusae Fossae (1)
|
|
This series of 4 images covers a portion of an outcrop of the Medusae Fossae Formation, a series of light-toned terrains in the Martian Mid-Latitudes. The Medusae Fossae has been and remains one of the most enigmatic features on Mars. The unit is characterized by wind-sculpted landforms, most notably eroded ridges known as yardangs. The composition of the Medusae Fossae is not known, but candidates include indurated (hardened) volcanic ash or remnants of dust-ice mixtures that formed in a different Martian climate. This HiRISE image reveals new details of the Medusae Fossae.
