D. H. Scott, and R. E. Eggleton, 19730101, Geologic map of the Rumker Quadrangle of the Moon: , https://doi.org/10.5066/P9FX3NN9.
Summary
The Rumker quadrangle, in the northwest quadrant of the Moon, is adjacent to the western rim of the multi-ring Imbrium basin and to Sinus Iridum, a large (220 km diameter) mare-filled crater. Both of these great depressions were probably formed by impact, as indicated here and elsewhere on the Moon by the characteristic form, distribution, and texture of surrounding materials and structures. The Imbrium basin and Iridium crater were filled by mare materials during the Imbrium and Eratosthenian Periods. In this quadrangle, the widespread ejecta blanket of the Imbrium basin, as well as the basin's concentric ridges and mountian rings, has largely been buried by terra materials of mixed origin and by ejecta from Iridum and numerous smaller [...]

Digitized 1:1,000,000-scale geologic map of the LAC23- Rumker 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.
