Schroeter Valley (Vallis Schroeteri) (Apr 13, 2003)
The Schroeter Valley is about 160 km long and 1000 m deep. On its complicated way from the "cobra-head" shaped part in the South to its other end somewhere in the north-western part of the visible area of the picture, its width varies between 5 km and 500 meters South of the valley, you can see the Herodot crater in the West as well as Aristarchus in the East. The walls of Aristarchus are about 3000 m high at a crater diameter of 40 kilometers.
