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

This one looked like petrified coral
