Mars Global Surveyor Mars Orbiter Camera

MGS MOC Release No. MOC2-1068, 21 April 2005

NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a plain covered by flow material that surrounded and banked against three older, rounded hills in the Zephyria region. Although some investigators have proposed that the flows covering plains in this region are the remains of an ice-covered lake, others have found considerable evidence, including small volcanoes, to suggest that the flows are volcanic. The textures on these flows resemble that of some of the lava flows in the volcanic Tharsis region of Mars.
