Although high elevation places like Alta ended up at 79 percent of …

Sunny skies and calm weather have a way of making the mountains feel quiet…as if nothing is going on. We can be lulled into thinking the snowpack is gaining strength and becoming more benign. But some of the most dangerous weak layers we deal with in Utah are born during these calm stretches — right at the snow surface.

On their own, they don’t pose an immediate avalanche …
