The volcanic plains to the east, southeast, and south of
the giant Tharsis volcano, Pavonis Mons, are dotted by
dozens of small volcanoes.
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC)
image shows an example
located near 2.1°S, 109.1°W.
The elongate depression in the lower left (southwest) quarter
of the image is the collapsed vent area for this small,
unnamed volcano. A slightly sinuous, leveed channel runs from
the depression toward the upper right (north-northeast); this is
the trace of a collapsed lava tube. The entire scene has been
mantled by dust, such that none of the original volcanic
rocks are exposed–except minor occurrences on the steepest slopes
in the vent area.
The scene is 3 km (1.9 mi) wide and
illuminated by sunlight from the left/upper 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.
