Quick report
-1030h -NNW Aspect -Slope Angle - 28* -Elevation - 10,220 ft -Air Temp - 40*F -Precip - 0 in last 24h but wind loaded snow throughout previous day and night -Partly Cloudy Came out to the BWRA to skin and ski multiple lines over a two day period. Stepped off at 0925 from our Leavitt Lake base camp. Sastrugi on the ground showcased that winds were primarily coming from the S and SW through the night. When we reached our objective we dug a snow pit and conducted a CT and an ECT. While digging our pit two snowmobiles ascended the route we intended to ski. Their sled penetration was only 10cm and gave us confidence that the snowpack was relatively stable. Of note, we observed these snowmobiles high mark nearly all rideable terrain in the area, on all aspects, with no issue. The data and results of our snow pit are listed below. We did multiple runs without observing any signs of instability. -Snow Depth - 220 cm -Firmness test 120-90cm 4F 90-0cm 1F -CT15 Planal Fracture at 90cm but column maintained structure and moved as a cohesive unit -ECT23 Planal Fracture again at 90cm but no propagation
Avalanche
Observed point release avalanches in multiple chutes above the treeline on slope angles above 40 degrees on N annd S aspects. No human interaction. Most only 100-300m in length
