Wind Erosion

Located east of Eumenides Dorsum, this VIS image contains evidence of long term wind action and erosion. This area of Mars is dominated by poorly cemented surface material that is easily eroded by the wind. Unidirectional winds have created the linear ridge/valley system at the top half of this image. These features are called yardangs. Studies of this area propose volcanic ash eruptions from nearby volcanoes are the source of the surface material.
