Comments

We noticed a long running avalanche in North Shumway canyon in the Wellsvilles.  The wind slab appeared to be 2-3 feet deep and at least 150 wide at the north east facing starting zone.   It looked like the slab was all new snow that had drifted in overnight.  This slide is a repeater and we've seen that canyon run full travel this year at least one other time.  We could see debris near the bottom of the canyon around 6400 feet.
