MGS MOC Release No. MOC2-503, 4 October 2003

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) picture shows the lobate fronts of a large flow or series of smaller flow features in Kasei Valles. The rubbly surface of the flow has been interpreted to suggest that this might have been a mud flow, rather than a lava flow, but final determination will someday require a person to visit this landform "in the field." This picture is illuminated from the right and covers an area approximately 8 km (5 miles) wide near 15.7°N, 77.7°W.
