This observation shows mid-latitude-type gullies and dark and light materials. There are dunes in this crater as well (east of the gully aprons). One of the more stunning features is the gully formation right outside the center swath of the full image.

At HiRISE resolution, we can examine whether there has been activity in the gullies that post-dates the placement of windblown materials, like boulders down the slopes. We can also gather information to help determine the processes responsible for gully formation.
