Quandary Sastrugi

Add to Cart Add to Lightbox Download

High on the eastern slope of Quandary Peak in the Colorado Rockies, I came across these bizarre shapes in the snow. Drifts several feet high were curved back over themselves, like waves frozen in time. Only recently when reading a book about Antarctica did I learn these formations have a name: 'Sastrugi'. Sastrugi are sharp irregular grooves or ridges formed by wind erosion. They are common in polar regions or other barren, windswept areas. Here at 13,000 feet there were no trees or any other barriers. The winds were relentless, gusting to 60+ mph and producing a wind chill far below zero. Sastrugi are known to make skiing very challenging, and the few skiers I saw on this day looked like they were having a rough time. In Antarctica sastrugi have even been blamed for plane crashes, since they make landings and takeoffs quite difficult. The peak visible in the distance is Red Mountain and down below is Highway 9 just before it crosses the Continental Divide. 2 additional 14’ers, Grays Peak and Torreys Peak, can be seen on the far left.
