Ventifact

Ventifact, with pocket knife for scale

Ventifacts are rocks which have been faceted (eroded) due to the sandblasting action of wind, usually in deserts.

This example was collected from an area between Yuma, Arizona and San Diego, California.

The dark color of the upper surface of this rock is desert varnish, a coating developed over time probably due to a combination of weathering and biological processes.
