Quick report
- Cracking
- isolated
• No recent avalanches observed. • No avalanches occurred in Shed 9 during last week’s cycle. • The crowns from the previously reported events in Shed 7, Path 1163, and the north face of Devils Hump were still partially visible. • Wind slabs were widespread above 5500’ but mostly unreactive to ski cuts. A few cuts produced 1-2’ fractures. • A new surface sun crust was beginning to form below 6000’ on previously sun-exposed slopes by late afternoon as these passed into the shade (easterly aspects). • Dug a snow pit in the upper reaches of Shed 9 at 6740’ elevation, SE aspect, 27° slope. o Total snow depth here was 51” with a poor structure snowpack, and unstable results in two stability tests. o ECTP x2 with moderate force on a layer of facets on top of the Feb. 6th crust (see pit profile). • Repeated an Extended Column Test in Shed 7 West at the same location as last Thursday (Feb. 29th). o Snow depth here was 71” with the Feb. 3rd crust now buried about 3 feet down. Structure was like that in Shed 9 with multiple facet/crust combo layers beginning about 20” down. o A few ECTNs in the upper 20”, but no fractures on the facet/crust combo layers deeper in the snowpack. Minimal obvious signs. Just some minor cracking in the recent wind slabs
