Barchan Pac-Man

Here is something interesting: a barchan dune filling the upwind portion of a small impact crater in a Pac-Man-like shape. This “dune-in-a-crater” is nearly at the highest extent of the field. It’s also probably a rare configuration, and over the next few tens of thousands of years the sand will be blown out of the crater. Enjoy it while it lasts!
