Gullies are found on some dunes.
 These are somewhat different than gullies in other places, like the walls of craters.
 Gullies on dunes seem to keep the same width for a long distance and often just end with a pit, instead of an apron.
 Many of these gullies are found on dunes in Russell (Martian crater).
