Highlights

Avalanche danger is LOW, and avalanches are unlikely. You'll find generally stable snow conditions.

Normal caution is recommended. Follow safe travel protocols and practice companion rescue with your backcountry partners.

    Very unlikely, dangerous avalanches failing on a persistent weak layer from November remain possible on slopes steeper than 30 degrees in high shady terrain with thin snow cover and poor snowpack structure.

    Up high and on slopes facing west, north, and east, avalanches failing on a persistent weak layer are possible in isolated outlying terrain where previously wind-drifted snow overlies weak, sugary snow from November.

Recent Activity

No avalanches were reported in the Logan Zone since a widespread natural cycle occurred on December 3 and 4.

Snow and Weather

The Tony Grove Snotel at 8400' reports 48 inches of total snow (126% of normal) with overnight temperatures in the mid-30s F. The new weather station on Paris Peak at 9500' in elevation reports 31° F and 20+ mph winds blowing from the southwest. We are doing pretty well compared to the average for those wondering where all the snow is. The snow depth last year was about the same as it is today. The black line is this season, and the orange line is last season.

In our travels yesterday, we found a variety of snow surfaces: sun crusts, wind crusts, rime crusts, surface hoar, and widespread, small grain facets. The persistent high pressure and temperature inversion are causing the surface snow and what's just beneath to weaken. This makes for fast and loud riding conditions now but is a potentially poor setup for the future. Coverage is good up high but still deceptively shallow at mid-elevations. Even DJ Osborne is waiting for a few more feet of snow before he veers too far off the beaten path.

Surface hoar is plentiful right now. You'll find this type of snow across the range in shaded, sheltered terrain, mostly at mid and upper elevations.

Expect mostly sunny skies in the mountains today, with 8500' high temperatures around 35° F and light winds blowing from the southwest. High-pressure conditions will continue through Monday, with sun and pretty warm temperatures in the mountains and haze in the valleys. Clouds and the chance for snow will increase gradually next week, with a series of weak systems beginning to affect our area around Tuesday.

Additional Info

This fall, we installed two new weather stations in the Logan Zone. The Paris Peak Weather Station (available HERE) and the Card Canyon Weather Station (available HERE)

We visited the site on Tuesday, and the Card Canyon weather station looks good and appears to be working well!
