God Bless the Groomers

It's a pretty lean snow season so far across the west.  A look at NRCS SNOTEL snow-water equivalent data for the contiguous western United States showing most major drainage basins running at or below median.

In northern Utah, there isn't a single SNOTEL at or above median.  The closest is Hickerson Park in the northeast Uinta Mountains (where median is pretty pathetic to begin with), which sits at 96%.

In the central Wasatch, Snowbird, Mill D, Brighton, and Thaynes Canyon are at 81%, 68%, 51%, and 56% of median.  Records at the snowbird SNOTEL go back to 1990.  We're currently running at about the 30th percentile for snow water equivalent since then, meaning that 30% of the seasons were below current levels and 70% were above.  30th percentile doesn't sound that bad, but the difference between 30th percentile and the absolute lowest year on record is only a couple of inches of SWE and not that much.

On the Park City side, Thaynes Canyon is even uglier.  Records go back to 1989 and this season almost has the lowest SWE on record (4.5" vs. 4").

Given instrument accuracy and the like, a half inch difference is essentially a dead heat for worst snowpack on record.

Keep in mind that the SNOTEL records don't include 1976/77, which is probably the worst snow year on record.  Nevertheless, the snowpack situation is pretty poor.  

Dare I say it?

2020.

The resorts though have snowmaking.  The real Christmas miracle is happening at Mountain Dell.  I've gotten in four or five days up there now and, as I drive up the canyon, I can hardly believe they are open.  Trails are limited with a 0 to 5 cm base, but the Mitten-Main loop "goes" and the thin spots can be avoided.  


God bless the groomers who have made it work with scant natural resources.

  1. Thanks for the kind words and plug for Mountain Dell. We work hard up there to create this resource for the community and I can assure you that snow shovels are required to keep the course continuous and open in these current conditions.
