Forecast for the Logan Area Mountains

Toby Weed
Issued by Toby Weed on
Friday morning, November 19, 2021
Several inches of new snow and drifting will cause rising avalanche danger in exposed upper elevation terrain this weekend. Shallow avalanches of wind drifted snow are unlikely today, but may be possible on some slopes up high facing the northern half of the compass where there is preexisting snow from October covering up the rocks and smoothing out the terrain. Even a small avalanche could pick up speed and run pretty far on the slick rime-crust. With extremely shallow snow covering up the rocks, any avalanche could be very dangerous. The shallowly buried, icy and rock-hard rime-crust means people could easily slip, fall, and slide rapidly out of control even on slopes that are normally easy to travel on.
  • Remember to always follow safe travel protocols. Go one person at a time in avalanche terrain, while the rest of your party watches from a safe area.
  • Now is a good time to check your avalanche rescue equipment, change the batteries on your beacons, and practice with your backcountry partners.
We will update this forecast as conditions warrant.

Weather and Snow
Snow is likely in the Bear River Mountains starting later this afternoon and continuing through tonight, with 5 to 9 inches of accumulation possible by tomorrow morning. Expect gusty southwest ridge-top winds today, veering from the northwest tonight and drifting the fresh snow. In the Central Bear River Range, an inch or two of heavily rimed snow or graupel from this week caps a stout and very slick rain-crust that formed last Friday, 11-12-2021. Steep slopes are difficult to travel on due to the slick crust, and people could easily lose footing, fall, pick up speed and slide out of control in many upper elevation areas. If you plan on a bigger mountain objective this weekend you may want to bring an ice-ax along for self belay.
Only an inch or two of new snow accumulated this week on a slick and solid rime ice-crust at upper elevations in the Central Bear River Range. In some areas, southwest winds scoured the new snow right off the icy layer. Campground Ridge (11-18-2021).
Here it looks like a skier slipped and slid a ways, clearing a strip of fresh snow off the hard and shiny 11-12 ice-crust. Beginner Bowl in the Tony Grove Area (11-18-21).

Additional Information
  • Be very careful, keep your speed down, and stay in control. Encounters with shallowly buried rocks or down trees in the early season have led to many season-ending injuries.
  • The Tony Grove Road is not maintained for wheeled vehicles in the winter season.
