MGS Views of Labyrinthus Noctis
September 29, 2003
Labyrinthus Noctis is near the crest of a large (many thousands of kilometers) updoming of the Martian crust, and the 2000 meter (6500 foot) deep canyons visible in these pictures are bounded by faults. Debris shed from the steep slopes has moved down into after the canyons opened. Small dunes are seen in the lowest area, beneath the high cliffs.
