Geologic map of the Lansberg P region of the Moon Lunar Orbiter Site III P-9, Oceanus Procellarum including Apollo landing site 7 (Apollo 12)

The Lansberg P region lies within a lowland area between Mare Cognitum and the main part of Oceanus Procellarum, about 135 km due south of the crater Reinhold. The Apollo 12 landing site is in the west-central part of the region and has been mapped in detail by Cannon (1969). Although the entire region is covered by cratered and rayed mare materials, the mare is almost entirely surrounded by the terrae and is probably relatively thin. Superposed on the mare are two rays from the crater Copernicus, many individual craters, and crater clusters.
