Kernpunkte

A MODERATE avalanche danger exists on many aspects and elevations. The danger is higher along the Wasatch Back near the Ant Knolls and upper Snake Creek and may more mirror the SLC area avalanche hazard. Human triggered avalanches 1-3 feet thick are possible and may be unsurvivable. Extra Caution is required on steep north to east facing slopes.

There are two buried persistent weak layers (PWL) in the snowpack:

1. The upper layer buried down 12-24 inches formed during cold, clear weather in late January and has been buried by recent storms and wind-drifted snow.

2. The lower layer, near the ground, formed in December and has caused large avalanches, including two fatalities during the Holiday Avalanche Cycle.. This layer is most problematic in steep rocky terrain or on repeater slopes that previously avalanched this winter (see recent avalanche activity photo).

Loose dry avalanches and pockety shallow soft slab avalanches may be triggered in steep terrain. These may be mitigated via ski cuts or cornice drops.

Recent Activity

On Saturday, a snowmobiler unintentionally triggered a large avalanche near the Ant Knolls. This avalanche was 3 feet deep, 250 feet wide, and easily could have been a very close call. This was on a steep northeast facing slope at 9300'. Lots of avalanches occurred in the Salt Lake and Park City mountains over the weekend. Other natural avalanches were reported in both the upper and lower Snake Creek areas of the Wasatch Back, perhaps 1-3' deep and hundreds of feet deep on northeast facing aspects.

Observations and Avalanches

Snow and Weather

Skies are clear with light westerly winds and temps in the single digits to mid-teens.

Today will offer sunny skies, light winds and temps rising to the upper teens to mid-20s. A weak system arrives tonight into tomorrow with a more potent system on Friday. Riding conditions are fair on sun and wind protected terrain.

Special Announcement

We are deeply saddened to report an avalanche fatality in the east bowl of Silver Fork of Big Cottonwood Canyon from Saturday. A very preliminary report can be found HERE.
