Ventifacts in the McMurdo Dry Valleys

A Ventifact is a stone that has been shaped, polished or faceted by wind driven sand. Antarctica can be a windy place and since the Dry Valleys has a lot of sand there are also allot of ventifacts.

Here are some photos of some of Dave's favorites he found during his walk.

This one is sandstone
