Schweitzer ski patrol is encouraging and offering weekly free "Transceiver Sundays" (clock tower at 10:00 a.m.) to all interested public with two permanent practice areas and one more difficult challenge that is on a less regular basis. All they ask is that the public covers up their tracks and if practicing digging techniques, please replace your divot. This is a great way to keep on your A game for those venturing out of bounds.
In the past 7 days snotel sites on the Kootenai have accumulated over 3 feet of new snow! This new snow has multiple weak interfaces that make for prime avalanche conditions. This new snow is under additional stress now that warm temps and rain have moved into the mountains. Smaller avalanches within this new snow have a high potential to step down to the weak surface hoar layer buried over 3 feet deep and create very large avalanches. These factors combined are setting the stage for VERY DANGEROUS CONDITIONS THROUGHOUT THE WEEKEND!
Backcountry skiers and snowmobilers are STRONGLY ADVISED TO AVOID GETTING ON OR NEAR STEEP TERRAIN. Avalanches are releasing naturally at this time on all aspects in terrain over 30 degrees, steep slopes and steep sided gullies are dangerous places in these conditions. Now is an easy time to make good, safe decisions. Play it safe this weekend and save the steep terrain for another day.
Join us Wednesday, February 15th at the Libby Middle High School for a 2 hour avalanche awareness presentation.
On Thursday February 9th we traveled to the Warming Hut in the Keeler-Rattle drainage. The first sign of avalanche danger is "Avalanches"! We observed a large debris pile at the base of Benning Mountain and fresh avalanche crowns on all aspects in our travels. It was raining hard as high as we could see with the Bear Mountain Snotel reporting a temperature of 37.5 degrees. Wet and miserable.
Fresh crown lines below Warming Hut. 5,500'.
I have not yet talked to the source but I have been hearing lots of rumors about a very close call and partial burial near Bear Mountain. Sounds like a slope slide well into the timber on lower angle terrain and partially buried two snowmobilers that were digging out a sled. This is a good reminder that we are in a time when avalanches have the potential to run far and large, the areas where one typically feels safe may not be. Remember to pay attention not only to the slope you are on but the slopes above you as well.
Backcountry Forecast from NWS Missoula issued:
320 AM MST Fri Feb 10 2017
A cold front today will cause snow levels to start to fall today
with mountain showers continuing for the next few days with
minimal accumulations. A ridge will build over the area this
weekend and most of next week allowing cold nights and warmer
days with freezing levels in the 4,000 to 6,000 ft range during
the day. The next system looks about a week out, and it will be a
warm wet one, but so far does not look nearly as wet as the last
one for our region.
