New in GRL: Sliding and Burrowing Blocks of CO2 Create Sinuous “Linear Dune Gullies” on Martian Dunes by Explosive Sublimation-Induced Particle Transport by RoeLofs et al 2025

Some of the dune fields on #Mars form unique parallel channels called "linear dune gullies." New evidence suggests that these channels were formed by sliding and burrowing blocks of CO2 ice, rather than by liquid water as previously theorized.
