HIPOD 19 Jan 2023: Bizarre Icy Landforms
The Martian middle latitudes reveal may strange landforms.
This image shows roundish landforms covered by polygons and surrounded by trenches. Some combination of ice expansion and contraction, sublimation, and flow may have created this landscape.

So cool. Are these anything like the frost polygons in the Arctic?

@Helical_Code Quite possibly since the mechanism for their formation (expansion and contraction of ice) is the same on both planets. But at least on Earth, it's water ice. Not sure which ice it might be in the image (CO2 or water.)

Oh thank you for this insight!
