Avalanche danger is low. The snowpack is capped off with a smooth, widespread crust. Exercise normal caution while traveling in the backcountry. There is potential for falling rime ice. A period of mostly clear skies and melt-freeze cycles lies ahead.

Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features.

Overall avalanche danger is low, but remain in the avalanche mindset. Think about weather, terrain, snowpack, and your ego. When the snow flies again, you'll be better prepared.

Cliff bands are caked with rime ice. Warm temperatures over the next couple of days could dislodge this ice causing it to tumble down upon you. Stay aware and keep you eyes up if ascending below these areas.

Recent Observations

Tuesday's storm capped the snowpack off with a widespread rain / wet snow crust. This inch thick crust was found at 9,200 ft yesterday. No doubt it extends higher. Oddly, it supports the weight of a snowmobile, but you'll punch through if walking. You might be able to ski on it if you wish to punish yourself with a scraping, teeth-chattering experience. Wait a few days. It may turn into a great spring-skiing situation.

Despite moderate winds, no snow was being transported at higher elevations, further indicating that the storm brought mostly wet snow or little snow at all elevations. Snow surfaces are mostly smooth with very little wind-effect.

Cliff bands are caked with rime. Icy rocks glisten in the sun. The snowpack is still thin in places above treeline. Plenty of rocks are exposed on the sides of ridges and moraines.

No signs of wind slabs or other obvious signs of avalanche danger were seen.

Weather and Current Conditions

Weather Summary

Settle in for a  period of mostly sunny weather accompanied by above freezing temperatures during the day, and near freezing temperatures at night. Today the temperature near treeline is expected to be rise to 50 °F and will only fall to 42 tonight. Yuck!

Those looking for some spring-like skiing in January may be rewarded soon, though temperatures are trending downward and the window to find that sun softened snow will narrow.
