Word of the Day: Sastrugi

"Sastrugi" is the obsessive skier's word of the day.

Sastrugi are ridges of snow formed when wind erodes and drifts the snow. Sometimes the wind undercuts a drift and what is left are beautiful and interesting sastrugi such as these. (Photographs courtesy of Ken Knowles, National Snow and Ice Data Center, University of Colorado, Boulder.)

Thank you, Mike Darrah, for expanding the obsessive skier's vocabulary!
