Extended Mission operations for the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) include opportunities that come up about 10 times a week to turn and point the MGS spacecraft so that MOC can photograph a feature of high scientific interest. Many of these images are targeted to the site of a previous MOC image, so that a stereoscopic (3-D) view can be obtained.

The stereo view, which requires red (left-eye) and blue (right-eye) 3-D glasses to be seen, covers an area approximately 2.3 km (1.4 mi) wide by 6.2 km (3.9 mi) long. The full-resolution view is seen at nearly 1.5 meters (5 ft) per pixel, a scale at which objects the size of airplanes and school buses might be seen.

The landscape revealed by the 3-D view is a rugged terrain with steep cliffs and no fresh impact craters. This terrain seems most un-Mars-like compared to the typical cratered and dusty views MOC has provided since it began taking data in September 1997. In fact, one of the MOC science team members remarked, "If I'd seen this landscape used in a movie about Mars five years ago, I'd have said the director had no clue what Mars is supposed to look like." An irregular depression with a flat, mottled, light-toned floor dominates the scene. Small dark ridges on the depression floor near the top center of the image are dunes or drifts formed by wind transport of sandy sediment. The sharp buttes, mesas, and steep cliffs are all indicators that this terrain consists of a broad exposure of martian bedrock. North is up and sunlight illuminates each picture from the left/upper left.
