Summary
This map is one in a series of 1:500,000 scale geologic maps initiated by the National Aeronautics and Space Administration to investigate areas of particular scientific interest on Mars, The West Mangala Valles area merits detailed geologic study because it contains several small channels whose ages can be determined relative to geologic units that range in age from early (Noachian) to late (Amazonian) Periods of martian history. Because the small channels are of three ages and channels of each age are of a geomophic type unique to that age, their study increases our understanding of the continuity of fluvial processes in the evolutionary history of Mars. For these reasons, part of the area is a proposed site for a simple return mission [...]

Digitized 1:500,000 - scale geologic map of the science study area 1B, West Mangala Valles region of mars. The scanned map sheet was imported into ArcMap and georeferenced to the more current 2001 THEMIS Odyssey Orbiter mission data. Contacts and geologic units were digitized and attributed based on type and unit name.
