This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows large, light-toned, ripple-like windblown bedforms in a portion of the giant flood channel complex, Maja Valles. Ripples such as these are very common on Mars but not very well understood. They are larger than most ripples on Earth, and smaller than typical dunes. They are usually old, and probably immobile, features. Sometimes, larger, dark sand dunes are seen riding over them (although that is not the case here). If similarly-sized ripples were to be investigated by a Mars rover, they would probably provide critical information that would help determine the nature of bedforms like these all over Mars. The Maja Valles scene shown here is located near 17.7N, 54.8W, and covers an area about 1.4 km (0.9 mi) wide. Sunlight illuminates the scene from the lower left.
