Most impressive are the low numbers in Utah and Colorado where there are many high elevation basins that are typically just past peak snowpack in late April. Observations from these states show only a few sites above 50% of average snowpack SWE.
At the Spud Mountain SNOTEL in the San Juan Mountains (10,660 ft), the snowpack was completely gone a few days ago.
The few sites in the San Juan Mountains that are above 50% of average snowpack SWE are all at or above 11,000 ft. At Wolf Creek Summit (11,000 ft), snowpack SWE was running near average through February, when Mother Nature put on the breaks for storms and flicked the warming switch. At this high altitude location, the average peak snowpack SWE occurs around May 1, but this year it appears like they are looking at a late March maximum.
In northern Utah, low elevation locations such as the Parley's Summit SNOTEL (7500 ft) are now snow free.
At higher elevations, the storms between heat waves have enabled the snowpack to cling to a precarious existence, at least on northerly aspects, as illustrated by the Snowbird SNOTEL.
This looks like a good year to plan a backpack or peak-bagging trip in places like the Uintas and Colorado Rockies where in many years snow tends to linger and block high elevation routes well into the summer. Baring a major pattern change, it will be a very early hiking season this year.
