Tractus Catena Collapse Pits

June 9, 2003
This chain of pits formed by collapse as faulting extended the upper crust in the Tractus Catena region of Mars. The layered bedrock can be seen in the upper walls of each pit in this Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image. The picture covers an area about 3 km (1.9 mi) wide near 28.5°N, 102.9°W. Sunlight illuminates the scene from the left.
