Rilles as far as the eye can see at Prinz

LROC Wide Angle Camera (WAC) mosaic of the rille-rich Prinz crater region, east of Aristarchus Plateau. Bench-like features are visible in the Prinz B depression and two flows originating in Prinz B converge just west of the arrow [NASA/GSFC/Arizona State University].

The bouldery, higher-reflectance mound in the central portion of this image is an island near the source region, Prinz B, for a short sinuous rille. The two rilles join at the triangular tip of this kipuka-like structure and flow northwestward for ~10 km. Image field of view is 500 meters [NASA/GSFC/Arizona State University].

The images highlight a fork on the western edge of Prinz B, a source depression for an unnamed rille. Image field of view is 2.5 kilometers [NASA/GSFC/Arizona State University].

Virtually traverse the Prinz region of the Moon in the 100 m/pixel LROC WAC mosaic and explore the Prinz B rilles joining in the full LROC NAC frame!

The dramatic morphology of the Prinz-Harbinger region is usually overshadowed by bright Aristarchus to its west (upper right), seen here fastened to the lunar frame available to users of Google Earth (v.6). The region's features are best seen at local sunrise or sunset since the relief reflects little differences in elevation. The ridge at right averages only 300 meters higher than the depths within nearby rilles [NASA/USGS/JAXA/SELENE/GSFC/Google/Arizona State University].
