HiRISE image: Equatorial gullies

Gully-like landforms, or ravines, are most common in the middle latitudes of Mars, but also occur in polar and equatorial latitudes. We see here an impact crater about 900 meters wide, with distinct gullies on all inner slopes except in the northwest sector of the crater. The crater formed on the side of an ancient channel, so the northwestern section slumped into the channel, so the slopes are not as steep. This region of Mars is called Libya Montes, near the equator on the south edge of the Isidis impact basin. These are typical gullies… [More at link]
