(RLC-9) Geologic map of the Sabine DM region of the moon

This 1:50,000 scale geolgic map is one of a series constructed at various scales from photographs trasmitted by the Ranger VII, VIII and IX spacecraft. The center of the map area is about 23 km southwest of the Ranger VIII (US Air Force Aeronautical Chart and Information Center Chart AIC 60C, Arago). In general, geologic maps of the moon portray similarities and differences in the characteristics of the lunar surface. These characteristics, mainly topography and albedo, probably depend on the nature of the underlying rock units and the manner in which they formed. Information about the lunar surface for this map was obtained mostly from the Ranger VIII photographs, which were taken with the setting sun approximately 15'' above the local horizon. A few phtographs from the Lunar Orbiters II and V, which were taken under a rising sun. 22 degreees and 20 degrees above the local horizon respectively, were used to fill in details around the margins of the map area where the Ranger data are poor.
