This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) red wide angle image shows much of Alba Patera, a low, broad shield volcano in northern Tharsis. The caldera complex--the pits formed by collapse at the volcano summit -- is located toward the bottom center of this image. Alba Patera is located at 41°N, 111°W. The area shown here is approximately 430 km (~270 mi) across and illuminated from the lower left.
