You can trigger an avalanche from a distance or below if connected to slopes steeper than about 30 degrees. Expect the avalanche danger to increase as a storm starts to impact the Park Range on Friday. Assume any steep slope with continuous snow on northerly and easterly aspects is dangerous with weak snow beneath a slab. You may not see natural avalanche activity, but you can easily trigger an avalanche two to four feet deep. Frequent cracking and collapsing highlights how sensitive the snowpack is. You can find safer travel below the treeline where there is less slab and on lower angled slopes.
