Antarctic Snow Dunes
Extensive snow dunes wrinkle the surface of large parts of East and West Antarctica. The dunes are up to 100 kilometers long and separated by 2 to 4 kilometers, but only a few meters high. Comparison of modern satellite images with images acquired four decades earlier reveals that the dunes are nearly motionless.
