central Wasatch, the ski areas reported stiff, stubborn wind slabs on a variety
of aspects and elevations with most 1-3’ in depth. Not surprisingly, backcountry reports were few
and far between, but we were able to trigger a large slide along the Hidden
Canyon/10,420’ ridgeline in upper BCC that was up to 1000’ wide, stepping down 5½’
deep to the November facets. It was a
heavily loaded north-facing slope at 9600’.
You should be able to find some good firewood from the downed trees up
there in the summer. A couple other 1’ x
50’ naturals were observed along the southern most end of the
Continued snow and wind will keep the backcountry dangerous on and below steep slopes at the mid and upper elevations. The new hard slabs may not rip out until you’re half way down the slope or until the 4th person crosses the slope. As evidenced from yesterday, the continued onslaught of wind and snow will allow any avalanche to potentially step down into the old dormant weak layers from November and December.
The current avalanche danger is CONSIDERABLE today on, or beneath, any steep slope with recent deposits of wind drifted snow. Human triggered slides will be probable and will have the potential to be large and extremely dangerous.
Snowfall should continue throughout the day with 6-8” of snow expected. Winds should continue to nuke from the southwest along the ridgelines to the tune of 30-40 mph. 8000’ highs will be near 30 with 10,000’ temps in the low twenties.
