Summary
The Wilhelm quadrangle lies along a mare highlands boundary west of the crater Tycho, southeast of Mare Humorum, and southwest of Mare Numbium. The outer scarp of the Orientale basin is 1200 km to the West-Northwest. The quadrangle is characterized by pitted and mantled appearing terra, which in the north is interrupted by patches of mare and in the south by several large pre-Imbrian craters. Most of the mare material occupies angular massif bounded depressions which are approximately concentric and radial to the basins that contain Mare Humorum and Mare Numbium. Most of the large craters are either partly subdued (Wurzelbauer, Montanari), the degree of subdual apparently resulting from a mantle of terra material of varying thickness.

Digitized 1:1,000,000-scale geologic map of the LAC111- Wilhelm Quadrangle 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.
