Sulci Gordii

July 3, 2004
NASA's Mars Global Surveyor shows rugged hills and mountains mantled by a blanket of fine dust in Sulci Gordii on Mars. Ripple-like dunes in the troughs between each hill or mountain have also been covered with dust.

The Sulci Gordii are a grouping of ridges -- almost like small, rocky mountains -- located east of the giant volcano, Olympus Mons. This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a 3 km (1.9 mi) -wide portion of the Sulci Gordii region. The rugged hills and mountains have been mantled by a blanket of fine dust. Ripple-like dunes in the troughs between each hill or mountain have also been covered with dust, indicating that they are inactive in the present martian environment. This image is located near 21.2°N, 124.2°W. Sunlight illuminates the scene from the lower left.
