Summary
This map is one of a series prepared from photographs transmitted by Ranger IX (Jet Propulsion Lab, 1966, pls A56-58, B70-82). It depicts the geology of some 724 sq km in the northeast part of the floor of Alphonsus (Diameter about 115 km), a typical flat-floored old terra crater or basin with a subdued rim. Similar basins abound in the south central terrae of the visible hemisphere and on the far side of the Moon. Alphonsus is of particular interest, however, because of a well developed interior rille system and associated dark-halo craters.

Digitized 1:50,000-scale geologic map of the RLC-15 Alphonsus GA region of the Moon. Originally mapped on Lunar Base Chart USAF-ACIC imagery. The scanned map sheet was imported into ArcMap and georeferenced to the more current 2013 global WAC mosaic basemap. Contacts and geologic units were digitized and attributed based on type and unit name.
