Schroteri Valley, from Lunar Orbiter 5 (3D)

Original caption:"Stereoscopic view of a part of Schroter's Valley, the meandering depression running from the upper right to the lower left corner of the anaglyph. This rille is about 7 Km wide and up to 1300 m deep. Within its flat floor is a second, sinuous rille whose tightly packed meandor loops are about 200 m deeper. The ridge that is seen in the upper left portion of the photograph is about 1600 m higher than the plateau surface into which the Valley is cut".
