Schroter's Valley 2

This is a detailed photo showing part of Schroter's Valley (see last image). It clearly shows a complex, highly contorted rille inside the Valley. Like many rivers on the Earth, this rille has many tight loops along its course. These loops are meanders, and they suggest a long-lived flow on a fairly flat surface. They also require active erosion of the valley floor. This channel may have partially melted its way into older lava flows. (Part of Apollo 15 image P-341.
