Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Friday - January 16, 2015 - 6:33am
bottom line

Stable snow conditions exist on most slopes, and the overall danger is LOW (level 1). Increasing southwest wind today will create heightened conditions and a MODERATE (level 2) danger, with triggered wind slab avalanches possible on drifted upper elevation slopes.

  • Evaluate the snow and terrain carefully.
  • Avoid wind deposited snow on slopes steeper than about 30 degrees.

special announcement

Special thanks to Buttar's and ArcticCat for hooking us up with the light and powerful M8000. This machine will make our field days more fun, safe, and productive and will significantly boost our outreach and education efforts.

We picked up and tried out the new sled last week.

The sled in action included in our new Practicing Companion Rescue video.........HERE

current conditions

The 8400' Tony Grove Snotel reports 57 inches of total snow containing 116% of average water for the date, and its 26 degrees this morning. You can find pretty nice shallow settled powder and dust-on-crust riding conditions in the Central Bear River Range these days. The snow is supportable in most areas and you can ride anywhere without sinking in very deeply. A bit more snow fell in the front canyons earlier in the week, but If you're looking for deeper powder conditions, the Wasatch and Unitas picked up twice as much.

recent activity

We noticed a couple fresh natural wind slabs and some fresh loose wet activity at upper elevations in the Tony Grove Area on Wednesday(1-14-15).

A fresh wind slab under the cliffs on the east side of Naomi Peak. (1-14-15)

Avalanche Problem 1
type aspect/elevation characteristics
over the next 24 hours

Triggered wind slab avalanches are possible on drifted upper elevation slopes, and increasing southwest wind will build new drifts and wind slabs at upper elevations today. Watch for and avoid wind slabs in exposed terrain at high elevations in and around terrain features like gullies, sub-ridges, and cliff bands. Drifts and wind slabs should be fairly obvious, consisting of stiffer snow, rounded, chalky looking, and perhaps hollow sounding, but an inch or two of new snow today could make them a bit less easy to see.


It'll be mostly cloudy today, with west-southwest winds averaging in the mid teens, a high temperature at 8500' around 34 degrees, and an inch or two of accumulation the afternoon.. Overnight low temperatures are expected to be around 21 degrees. winds will be from the west-northwest, and a couple more inches of snow might fall. Looks like it'll be partly sunny and fairly warm in the mountains tomorrow.
