Additional Info & Media

Avalanche season begins with the first layer of snow. The sliding surface can be slick grassy slopes under the new snow, or old firn/ice in glaciated areas and permanent snowfields. It’s time to dust off your beacons, shovels, probes, and skills. Start looking at the terrain with “Avalanche Eyeballs.” Early season can be a dangerous time of year. The danger will increase with any new snowfalls or wind events this month.

Fish Creek Knob tour: partly cloudy/light north wind/-6C Thin early season-like coverage, <80cm total snowpack depth. Thin thermal crust at surface. 35cm F-4F storm snow settling over old facets and crust/facet sandwich. Variable test results with failure in 2mm facets above crust. Propagation potential is questionable with fracture character ranging from sudden planar to stepped breaks. Wind affected near ridge lines. Chose not to continue up ridge past 2400' due to hard windslab over facets. Skiied N-NE glades.

Storm totals approx 24" just below the ridge line. Thin radiation refreeze crust on surface and continued wet/warm snowpack below. Weak layer on an isolated column was 4-5" above the ground on a thin layer of facets with Q2 shear.

Isothermal snowpack up to about 2500ft or higher. Approx 12-14" new at 2700ft. Two natural slides that started in steep trees in warm temps that propogated out on weak layers covering the cat track at Eaglecrest. Lots of "whoomping" at 2700ft. Couldn't isolate a column today due to weakness/facets below the new/heavy snow.

I skied McGinnis via the winter route to get a look at the snowpack above tree line before this latest precip event. I didn't did a pit. General observation: Snow depth above 2300ft was generally 1-2ft. Hard crust at ground capped with 8-10" facets. Then very thin crust layer capped with another 2-3" facets. Pockets of wind slabs that were stable on this day. In Summary: A very weak supportable layer that is now buried and likely very sensitive.

55 cm snow. 15 cm weak 4 finger base layer with stronger 15cm 1 finger layer over top. 25cm of 4 finger loose snow on top. Weak layer collapse in tests but dues not fail in ECT>
