Giant Gullies

January 23, 2014
This image shows gullies that are large even by Mars standards, and much larger than the terrestrial landforms we call gullies. The length of some of these is over 6 kilometers (3.6 miles).

They are located on large mountains located north of the Argyre impact basin. An enhanced color view (reduced scale) shows only subtle color differences.
