Nilosyrtis Mensae Valleys and Boulders in the Fretted Terrain

Red Rover Science Team Caption: "This image was taken in the fretted terrain area located in the middle latitudes of Mars. Interesting features in this area are dunes, valleys, and mysterious black boulders that are as big as 15 to 25 meters (49 to 82 feet). The puzzling position of these mysterious rocks and the lack of our ability to understand how they got there reminds us how much there is still left to discover about our mystery planet."

The picture is a portion of MGS MOC narrow angle image E01-00878. The picture, acquired February 14, 2001, is located at 31.2°N, 289.5°W, and is illuminated from the left. The high resolution image covers an area 3 km by 4.9 km (1.9 mi by 3.0 mi) at 3.7 meters (12 feet) per pixel.
