Layered Yardangs in Henry Crater
June 12, 2003
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows wind-sculpted remnants of layered sedimentary rock that once completely covered the northwestern floor of Henry Crater, an ancient impact basin located at 11.7°N, 336.4°W. These landforms, shaped somewhat like inverted boat hulls, are textbook examples of a wind erosion form known as a yardang. The image covers an area 2.3 km (1.4 mi) wide; sunlight illuminates the scene from the left.
