Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Tuesday - November 29, 2016 - 5:48am
bottom line

Dangerous avalanche conditions likely exist at upper elevations in the backcountry. Avoid travel on or under drifted slopes steeper than about 30 degrees.

  • Very shallow early season snow cover exists in the backcountry, and hitting rocks is a serious concern.
  • 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

The Tony Grove Snotel at 8400' reports 17 degrees this morning and significant accumulations of new snow containing 2 inches of SWE (snow water equivalent) in the past couple days. Northwest winds moderated overnight at 9700' at the CSI Logan Peak weather station, and I'm reading 7 mph from the west-northwest and a chilly 9 degrees F. You'll find close to a couple feet of nice fresh powder at upper elevations in the backcountry. Careful because there is no solid base to keep you off the rocks, with all but due north facing slopes completely bare of snow before Thanksgiving.

Periods of very heavy snowfall and strong wind in the past couple days certainly helped to fill in the rocky terrain


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 and conditions deteriorated significantly with the storm in the past couple days. If you attempt the drive in your 4x4, be prepared with shovel and winter survival gear. Beaver Mountain welcomes up-hill traffic this time of year as it helps to pack out the slopes, but you should consider it as "backcountry terrain" before they open the lifts to the public.


recent activity

No avalanches were yet reported locally, but Snow Safety operations throughout the Wasatch mountains yesterday reported widespread new snow activity from both ski cuts and explosives, up to 12” deep. In the afternoon, when the higher precipitation rates kicked in, natural avalanches were reported on a variety of aspects, including both northerly and southerly. In the Ogden area mountains, one triggered slide failed on the facets on the ground.

Deep slabs, failing on old faceted basal snow are possible on some smooth north facing slopes at upper elevations. Pay attention to signs of instability like cracking or collapsing.
