BRIEF DESCRIPTION
South-western part of Mare Imbrium with numerous rinkle ridges and a network of bright streaks radiating mainly from the craters Copernicus and Aristarchus. An interesting object for larger telescopes is the system of sinuous rilles near the crater Prinz. Refer to your Antonin Rukl lunar atlas chart, page 65.
