Forecast for the Logan Area Mountains

Toby Weed
Issued by Toby Weed on
Wednesday morning, November 23, 2022
The snow on the ground is very weak, but it's generally stable and avalanches remain unlikely. Even so, people might trigger small avalanches of loose or wind drifted snow on very steep slopes.
  • Now is a good time to visit the backcountry, but caution is required due to shallow early season conditions.
  • The snow is still so shallow that people could be seriously hurt if they are caught and carried over rocks in even a small avalanche.
We will be issuing intermittent updates and publishing backcountry observations as they arrive. Please let us know what you think the danger is and send us your observations from the backcountry HERE

Weather and Snow
An inch of new snow is welcome, but it won't change things much. Cold and rather dry weather will persist through a breezy Thanksgiving weekend, but it looks like a storm and a bit of snow is likely on Monday. We are about due for a change in the weather... For more details and current conditions, visit the UAC Logan Weather Page HERE

Feathers of surface hoar are widespread on the snow surface across the zone. Paige found these in Logan Canyon on Monday.
The extreme temperature differences in the shallow snow caused by cold air is causing the snow grains to become weak and faceted (or sugar-like).
Shallow early season snow conditions exist across the Logan Zone, with only about a foot-and-a-half to three feet of total snow covering the rocks on upper elevation slopes. Although the sugary snow keeps you off the ground for the most part, there are numerous shallowly buried land mines out there. The snow is especially loose and sugary around rocks. Local snowmobile mechanics report a good number of A-arm replacements recently.
  • Keep your speed down! Caution is required to avoid hitting shallowly buried rocks, stumps, or down trees.

Avalanche Problem #1
Normal Caution
Type
Location
Likelihood
Size
Description
The snow surface is quite variable across the zone, with wind and sun crusts, and loud powder made up of feathery surface hoar and sugary near surface facets.
Now is a good time to get out into the backcountry, and although you'll encounter variable surface snow, observers are still finding pretty good "loud powder" conditions on sunny and shady slopes across the Logan Zone. Some surface crusts have formed in sunny and wind exposed terrain.
The snow is stable on most slopes and avalanches are unlikely. Even so, people should use normal caution in the backcountry because they could trigger small avalanches of loose or wind drifted snow on very steep upper elevation slopes.
Avalanche Problem #2
Wind Drifted Snow
Type
Location
Likelihood
Size
Description
People could trigger small slab avalanches of wind drifted snow if they venture onto exposed upper elevation slopes. It is always wise to avoid travel on steep slopes with obvious deposits of wind drifted snow.
  • Suspect wind drifts or wind slabs are often smooth and rounded looking, like lenses or flying saucers.
  • Wind slabs often form on the lee side of exposed ridges and in and around terrain features. Watch for and avoid drifts on gully walls, under cliff bands, along sub-ridges, in scoops, saddles, and sinks.
  • Drifted snow is stiffer and more compacted than non-drifted snow, and hard drifts often produce hollow drum-like sounds when you walk on them.
  • Freshly formed wind slabs can be quite sensitive and are often remotely triggered. Older, harder wind slabs can be very stubborn and may not release until you get well out on them, suddenly failing like a big mouse trap.
  • Shooting cracks in drifted snow are a sure sign of instability.
Additional Information
  • Take the all-new online avalanche courses the UAC built for Know Before You Go or take other online courses listed on the KBYG website (Develop skills -> Online Learning).
  • Get your avalanche rescue gear ready for winter. Put fresh batteries in your transceiver and update the firmware. Inspect your shovel and probe. Get your airbag backpack ready by possibly doing a test deployment and update the firmware if it is an electric version.
