Equatorial Gullies

April 21, 2014
Although gullies are most common in the middle latitudes of Mars, they are also found in equatorial regions. This image shows a 3-kilometer-wide impact crater with gullies all along the steep inner slopes.

An enhanced-color cutout better distinguishes the gully deposits from the surrounding boulder fields. These slopes are very steep, so a fluid like water is not required to explain gully formation.
