Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Sunday - November 27, 2016 - 5:08am
bottom line

Expect a rising avalanche danger during the storm as snow accumulates and is drifted onto steep upper elevation slopes. Wind slab and persistent slab avalanches are possible at upper elevations in drifted terrain and on smooth north facing slopes with preexisting snow. The danger of storm snow avalanches will increase with significant accumulations and continuing wind.

  • Very shallow early season snow cover exists in the backcountry, and hitting rocks is perhaps still more a concern than potential avalanche danger.
  • You don't want to take a ride even in a small avalanche, as you could easily be injured with the shallow snow hardly covering up the rocks and dead-fall in avalanche runout zones.

current conditions

Expect to find very shallow early season conditions, with all but due north facing slopes completely bare of snow before last week. There's only a few inches covering the rocks up at Tony Grove, and 9 inches of total snow on the ground at 8200' at the Franklin Basin Snotel just north of the state line. It's 19 degrees this morning at 9700' on Logan Peak, with sustained 30 mph+ winds overnight from the south-southeast, with gusts pushing 50 mph.

Remember, the Tony Grove Road is a busy shared use area, so you have to watch your speed around pedestrians and dogs. The road is not maintained for driving in the winter, so if you attempt the drive in your 4x4, be prepaired with shovel and winter survival gear...

The early season is a great time to refresh yourself and practice companion rescue techniques with your partners.

recent activity

A party in the Tony Grove Area reported some subtle audible collapsing in north facing terrain at around 9000' on Thanksgiving Day. No avalanches were reported locally, but a skier triggered avalanche and a small natural avalanche cycle occurred this week at upper elevations in the Central Wasatch Range...
