Less Info

Frozen dunes in Victoria Valley, in the Dry Valley region of Antarctica. Located 500 meters above sea level near the Ross Sea, it is raked by strong katabatic winds that can reach speeds of 115 km/hour. This is the only dune field in Antarctica, and much of it is permanently frozen. Satellite imagery shows that their upper surface is slowly migrating 1.5 meters per year. The Dry Valleys are a rare window into processes that are shaping frozen arid environments on Mars and other planets.
