This image finally completes a stereo pair with another observation acquired in 2007. It shows a fresh (well-preserved) landslide scarp and rocky deposit off the edge of a streamlined mesa in Simud Valles, a giant outflow channel carved by ancient floods.

The stereo images can be used to measure the topography, which in turn constrains models for the strength of the mesa’s bedrock. Do look at the stereo anaglyph.

This is a stereo pair with PSP_005701_1920.
