Quick report

Skied from 5300' to the ridge line at approximately 6800', with temperatures under 20F much of the day, with next to no wind. There was 4"-5" new from the day before at 5300' and 5"-6" new above 6000'. This snow sat on the 6"-8" from earlier in the week. No cracking or whoompfing. Stability tests: I dug to the crust layer that was ~15" into the snow pack. The top 14" was soft powder, fist hard. The inch or so on top of the frozen rain crust layer was stiffer, but bonding well to the crust. The crust was ~8" thick and P/K hardness. Under the crust was soft facets (think snow cone without the flavoring). (You can see in photo where I scooped them out with my finger.) At ~6500'...CT15 @ 8", CT19@14" I also did a couple old school shovel shears which were moderate/moderate hard and sheared clean at the 14" layer. All-in-all, I judged it as pretty safe ski conditions as that crust is a strong bridge at this point. Sledders and snow bikes should treat it with caution if they find they are breaking through the crust as they test their way up the slopes as there is not support underneath. I skied a W NW treed slope, An East-facing open slope and a North-facing gully, all with some portions being over 30 degrees. No signs of instability.

Avalanche

Old debris piles were still visible under the new snow. New snow sloughs could be seen off steeper slopes on East and West faces. All natural, from the previous day.
