Terraces in Eratosthenes Crater

December 5, 2012
Like many complex craters on the Moon, Eratosthenes exhibits terraces (upper left) within its rim. Terraces form as the walls of the crater slump down, creating a landslide while leaving the upper portion of the wall intact. LROC NAC image M119924207R; image width is 600 m.
