Martian ‘Linear Dune Gullies’ are Created by Sliding Blocks of Carbon Dioxide Ice, Researchers Find
Two examples of Martian dunes with linear dune gullies: (a) linear dune gullies on a dune field in Galle crater; (b) linear dune gullies on a dune field in an unnamed crater in the center of Hellas Planitia. Image credit: Roelofs et al., doi: 10.1029/2024GL112860.

On some of the dune fields on Mars, parallel channels, called linear dune gullies, are found. Contrary to their name these gullies are often highly sinuous.
