“Very dangerous avalanche conditions exist in the Vail and Summit County and the Front Range zones. Human-triggered avalanches are very likely near and above treeline. One to two feet of new and wind-blown snow are loading weak layers deeper in the snowpack. Multiple parties triggered avalanches in the last two days and CAIC forecasters reported natural avalanche activity this morning. It is possible to trigger avalanche from lower down on slopes, from adjacent slopes, or from a distance. You can reduce your risk of being caught in a deadly avalanche by staying off of and out from under slopes steeper than about 30 degrees. Travel in avalanche terrain is not recommended.” – CAIC, today
