HiPOD 1 June 2023: Dune Gullies of Russell Crater

We’ve seen blocks of carbon dioxide ice in these gullies several times in previous images, which are likely carving out the linear gullies. This observation is part of a potential series to try to determine: 1) how long individual blocks last; 2) whether they stop and restart, or only move once. Russell Crater is located in Noachis Terra, a southern landmass to the west of the Hellas impact basin.
