Location: Huntington Ravine “The Fan”

On the lower fetch of “The Fan” in Huntington Ravine the temperature was 32.4 F degrees. A few scattered clouds. Light winds from the southwest at ground level, but higher in the terrain swirling moderate gusts were creating blowing snow and spin drifts. At our pit location we found the snowpack to be 127cm deep, elsewhere the depth varied significantly. This area was actively being top loaded and cross-loaded with blowing snow. The snowpack is mostly comprised of decomposing fragments of snow that have been broken down by the wind and redeposited. The bottom of the pack is refrozen clustered rounds and ice, the results of a rain event in mid-December. Overall the snowpack is thin with much exposed rock and ice. Isolated pockets of wind drifted snow have accumulated lower on the ravine walls and in drainage features. There is uncertainty about the snowpack in many of the ski run starting zones. Our stability tests gave no alarming results and no new avalanches were observed. Drifted layers of wind blown snow in isolated terrain features could produce small skier triggered avalanches.
