Weather Comments
At and above treeline, west winds were strong enough to swing whole trees in motion. Below treeline, winds were near zero. Temps were in the low 30's throughout the day.

Snow Characteristics Comments
The recent storm drastically improved travel conditions, although bushes and grasses are still halfway covered. At and above treeline, winds have created supportable surfaces easy for travel.

Increasing Danger
Problem #1 Comments
Faceted, old snow can easily be found at the bottom of the snowpack on mid and upper-elevation polar slopes. No recent avalanches were observed, and signs of instability will not make themselves known unless you dig to the ground. With active wind-loading, I put this trend as increasing.

Wind Drifted Snow
Trend
Decreasing Danger
Problem #2 Comments
Winds from the past few days have moved snow and sculpted supportable and hard wind drifts on leeward slopes. Available snow for transport is diminishing, but today's wind was moving what dry snow remains on the snow surface.

Comments
Today I traveled to Cutler Ridge to examine mid and upper-elevation slopes holding weak, sugary snow beneath the recent storm snow. Surface hoar was observed on all shady slopes that were sheltered from the wind, but it had been destroyed by strong winds at and above treeline. Winds have been moving a lot of snow over the past few days, and although snow available for transport is dwindling, today’s winds were pushing the remaining soft snow into supportable, hard wind drifts. No recent avalanches were observed.
I dug on a wind-loaded northeast slope at 8,000’ and found faceted snow 75cm beneath the surface. An extended column test resulted in propagation on a layer of graupel that fell early in the last storm (ECTP-13 62cm beneath the surface). While the PWL is not showing obvious signs of instability, quickly digging to the ground reveals a poor structure, indicating a setup that strongly suggests “stick to low-angle terrain!”. I would expect wind drifts along the ridgeline to be 3-5’ deep, delicately resting on the weak snow from earlier in the season.
