This en:Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) wide angle color composite image, obtained in December 2003, shows the middle of the three Tharsis Montes, en:Pavonis Mons. This is a broad shield volcano--similar to the volcanoes of Hawaii--located on the martian equator at 113°W. The volcano summit is near 14 km (~8.7 mi) above the martian datum (0 elevation); the central caldera (crater near center of image) is about 45 km (~28 mi.) across and about 4.5 km (~2.8 mi.) deep. Sunlight illuminates the scene from the lower left.
