Geological Chronicle
Darwin is a complex lunar impact crater classified as a walled plain in the Moon’s southeastern part. From Earth, it appears significantly foreshortened because it lies close to the limb. The northern and southern parts of its outer rim are all but destroyed, while the eastern rim is worn but intact. all but destroyed
Parts of the floor have been resurfaced. The southern floor is only roughly level, and a dune-like set of hills lies in the northeast. The source describes those hills as decelerated surface-flow ejecta from the Orientale basin impact, which struck the eastern rim. In the west, a low, somewhat irregular dome is one of the few lunar domes outside a mare and the largest on the Moon’s near side. the largest lunar dome on the Moon’s near side
A system of rilles cuts across Darwin’s northern floor, crosses the eastern rim and continues southeast. Called the Rimae Darwin, it stretches about 280 kilometers and is 1–2 kilometers wide. East of Darwin, it crosses Rima Sirsalis, which runs northeast. about 280 kilometers
