It's really, really snowy in there this year.

Be prepared for lots of snowy mixed until mid-July at the earliest. Nearby snow pillows are recording near-record depths.
The snow pillow data shows us that as of today, snow water equivalent (roughly the depth of the snowpack, although it is weight rather than depth actually) is four times average values for this time of year.
