HiPOD 26 May 2023: Fans Both Light and Dark
This image is part of a longterm seasonal monitoring site with lots of long bright and dark fans. These are formed as a result of sublimation, when subsurface ice is transformed by sunlight into a gaseous state and exposes the underneath darker material. This is subsequently blown about by the wind and the fans will fade over time.
