Small Tharsis Volcano

Aug. 30, 2004
NASA's Mars Global Surveyor shows a small volcano located southwest of the giant volcano, Pavonis Mons on Mars. Lava flows emanate from the summit region into an irregularly-shaped collapse pit, or caldera. A blanket of dust mantles this volcano.

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a small volcano located southwest of the giant volcano, Pavonis Mons, near 2.5°S, 109.4°W. Lava flows can be seen to have emanated from the summit region, which today is an irregularly-shaped collapse pit, or caldera. A blanket of dust mantles this volcano. Dust covers most martian volcanoes, none of which are young or active today. This picture covers an area about 3 km (1.9 mi) across; sunlight illuminates the scene from the left.
