The Flamsteed K region is in the southern part of Oceanus Procellarum , approximately 60 km (kilom eters) north of the crater Flamsteed and 330 km southwest of the crater Kepler. The region was photographed by Lunar Orbiters I and III ; it includes the landing site of Surveyor I and a potential early Apollo landing site. The area is included in a 1:1,000,000-scale map by Marshall (1962).
This map shows the geology in and around two potential early Apollo landing sites in the equatorial belt. The Wichmann CA region is in the Oceanus Procellarum, south of the equator, approximately 320 km south of the crater Kepler. It is covered by mare material with numerous ridges, low domes, craters, and crater clusters. Relatively few of the craters are larger than 200 m across. Terra material is absent. The relative freshness of the low domes and prominent mare ridges suggest that the mare material here is relatively young. On an earlier, small-scale reconnaissance geologic map of the Letronne region (Marshall, 1963), mare material in the Wichmann CA region was mapped as Imbrian; but Orbiter photographs show that the oldest craters on the surface are relatively young Eratosthenian craters and mare material is now believed to be Eratosthenian.
The Lansberg P region lies within a lowland area between Mare Cognit um 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.
