Avalanches: Widespread shooting cracks at all elevations and aspects up and down. All of this and the following was in the storm snow, no evidence of activity further down in the snowpack until the end of the tour:
Intentionally triggered by ski cut r2d1 slide in rock. Ski cuts on big produced widespread cracking and r1d1. Natural r2d1 in big looked like it ran late in the overnight storm. Skier triggered r2d1 on the last convexity in big, not surprising. Remote triggered r1d1 slide on the south aspect from the ridge.
multiple natural r1d1.5 slides on the northeast aspect wrapping back around toward friendly finish, appeared to go late in the overnight storm. It looked like the face above friendly finish that often rips has not yet, so it’s probably ripe to go.
Weather: blowing wind and snow, s-3 and maybe more – 5 inches on the car and sleds after 4 hours out in the morning
Snowpack: New snow 14-16 inches, plus the 5 or so that fell during the morning. Consistent midstorm instability 4-6 inches down, 8 or more inches down by the end of the tour. Didn’t investigate closely, maybe due to upside down heavy morning snow on top of lighter snow during the night?

Avalanches: Widespread storm slab instability cracking and sliding 15cm deep, full width running 3/4 to full track. Mostly D1’s w/ a couple D1.5’s
Weather: Snowy & Blowy. HST 16″ w/ 1.8″ SWE at 16:00 and still snowing.
Snowpack:

Avalanches: Watched a power cloud hit the willows at the upper valley transition below the East Face of Gothic. Poor visibility, D2.5-3 estimate.
Weather: Snow intensity decreased throughout the day. S2 becoming s-1 by 3-4pm. Generally light winds in valley. Extreme gusts developing at 5pm and temps dropping.
Snowpack: Didn’t really get off the road. Didn’t observe anything significant on this front.

Avalanches: Very little margin for error in terrain selection today.
Below treeline, we observed widespread natural storm slab avalanches and skier triggered a handful, all small in size. SS-N/ASc-R1-D1/1.5-S
Near treeline, we observed two large natural persistent slabs, 2 to 3 feet deep, failing on facets near the ground. One on a NE aspect and one on a SE aspect. SS-N-R2-D2.5-O. We also remotely triggered 2 large persistent slab avalanches from ridgelines ~1-4 feet deep on the ground, one of which was triggered by a remote cornice fall. NE and N aspects near treeline. Debris ran far into flats and snapped numerous small trees. SS-ASr-R2-D2/2.5-O. Video to come.
Weather: Pacific northwest!! S2 most of the day with stronger pulses at time. Light winds below treeline, strong to extreme winds above treeline from NW and SW. Intense snow transport during gusts. Warm.
Snowpack: 45cm of dense, new snow over well-documented PS structure, weak snow near the ground. Ski pen ~shin to knee deep. Lots of moderate collapsing, a few large collapses on various aspects. Widespread cracking on a density difference (stellar dendrites) mid storm, about 20 to 25 cm deep.

Avalanches:
Weather: The mechanical water read-out from 5 a.m. was late to record the data so the water equivalent I gave earlier was low. So the 24 hour total (14 hours really since it started at 5) is 11 1/2″ new snow with 1.00″ of water. Snowpack at 33″. Wind is starting to pick up a little but still light at 2-4 SW but some gusts are just starting up. Snow is letting up a little as well. Temp. holding steady at 28F. No visibility. billy

Avalanches:
Weather: Thankfully very light wind but s steady moderate to heavy snow fall with 9½” overnight and 0.68″ of water (though that may be a bit behind the snow total by a little). Snowpack is at winters deepest of 32″. Temperature very warm with overnight range 28 to 30. I will getg you actually totals around 7 or so.
