Erosive winds have removed large volumes of material in this Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image to form yardang ridges. The most classic yardang shape is that of the inverted boat hull; each of these streamlined hills provides a near-textbook example. The landforms are found in the Medusae Sulci region near 5.7°S, 159.8°W. The image covers an area about 3 km (1.9 mi) wide, and is illuminated by sunlight from the lower left.
