NASA LRO Image: Inside Ryder Crater

Ryder crater is rather oddly shaped; is it two craters or one? It is 17 km in the long direction and 13 km in its shortest dimension. The western floor of the crater is about 1500 meters below the western rim, while the eastern rim is 3000 meters above the same floor. The eastern shelf, seen in today's Featured Image, is 5000 meters above the western rim!
