Active sand dunes are common on Mars, and have a variety of surface textures. The "braided" texture visible here may be typical of dunes that are transitioning into sand sheets.

Also see this image for a Context Camera view of this area.

The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. (The original image scale is 58.3 centimeters [23.0 inches] per pixel [with 2 x 2 binning]; objects on the order of 175 centimeters [68.9 inches] across are resolved.) North is up.

This is a stereo pair with ESP_060855_1700.
