Comments

I noticed a ton of avalanche activity on the Wellsville’s as I drove through the canyon this afternoon. Most aspects from northeast to south has roller balled and wet sluffs had come down nearly every drainage. Some of the wet sluffs appeared to have run 1000+ vert and left a bit of a pile at the bottom.
The most interesting of the slides I saw was off the southeast slope of the Wellsville cone. A wet sluff started near the peak and ran approximately 600 vertical. At that point it overloaded a recent weak layer and a soft slab released 200-300 feet wide and 1-2 feet deep that ran to the bottom of the slope another 400 vertical feet below. This was the only slab I saw release on the Wellsville’s but were there’s one there could easily be more. I wish I could have taken a picture because it was a pretty interesting looking slide.
