The Moon
Sinuous Rilles East Of The Aristarchus Plateau

Apollo 15 metric camera picture of sinuous rilles (at bottom of image) east of the Moon's Aristarchus Plateau. The rilles have the appearance of lava channels or collapsed lava tubes, and most originate on craters. The largest rille in this southward-looking oblique view is Rima Prinz, which starts at the center of the image at the crater Prinz (25.5 N, 44.1 W; 46 km in diameter) and trends generally northward (down). Oceanus Procellarum is at upper left and the bright 40 km diameter Aristarchus crater is at upper right, at 24 N, 47 W. (Apollo 15, AS15-2606)
