Mega Dunes

Mega 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 the height is only a few meters. The dunes are unique in that they appear not to be formed by normal wind depositon, but rather by ablation due to wave patterns set up in katabatic winds.
