In many places, Mars' northern lowlands are separated from its southern highlands by "fretted terrain," a landscape of steep cliffs and table mountains, or mesas. Here, in an area named Deuteronilus Mensae, which is considerably north of the equator, the mesas have strangely textured aprons at their feet. Many lines of evidence suggest that these aprons contain ice underneath the dust and rock visible at the surface. The image is about 200 kilometers wide.

This is a red-blue anaglyph. Use 3D glasses (red over left eye, blue over right) to see it in 3D.
Source data was Level 3, meaning that it has all been reprojected onto a MOLA topographic map. That has the effect of removing large-scale topography (regional slopes and the larger topographic features, including the mesas) while leaving in small-scale topography (crater rims, cliff scarps, et cetera). Differences in illumination probably result from different path lengths through the atmosphere? The left-eye (red, in the anaglyph) image is stereo channel 2, the right-eye image stereo channel 1. The image has been rotated to place north at left in order to make the stereo sensible to the human eye.
