Ventifacts are stones faceted by years of sandblasting wind

In windy arid plains, flying sand abrades exposed cobbles into ventifacts — stones with polished faces and sharp edges cut by abrasion.

A shift in wind direction can add a new facet, so some rocks become miniature pyramids recording climate history in their geometry.

Grit is a slow lathe. Ventifacts prove desert wind does not only build dunes; it also machines the pebbles underfoot.
