NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC)
image shows a grouping of mesas created by pitting and
erosion of a layered material north of Apollinaris Patera
near 1.7°S, 187.0°W. The terrain is mantled by dust
and the troughs between the mesas exhibit large, ripple-like,
windblown bedforms.
The picture covers an area 3 km (1.9 mi) across.
Sunlight illuminates the scene from the lower left.

Malin Space Science Systems and the California Institute of Technology
built the MOC using spare hardware from the Mars Observer mission.
MSSS operates the camera from its facilities in San Diego, California.
The Jet Propulsion Laboratory’s Mars Surveyor Operations Project
operates the Mars Global Surveyor spacecraft with its industrial
partner, Lockheed Martin Astronautics, from facilities in Pasadena,
California and Denver, Colorado.
