Gullies and Lobate Material in a Crater in Nereidum Montes (3-D)

May 24, 2012
This crater has gullies on its southwest-facing walls and rim, as well as and what appears to be two separate instances of lobate (ear-shaped) material associated to its interior gullies.
This observation is a "ride-along" with the CTX Camera, which has a much larger footprint, but lower resolution than the HiRISE camera.
With much better resolution than CTX, HiRISE may be able to provide insight into the relationship between the features.
