Observer Comments

A recent cornice fall with a large debris pile was seen at the very back of the valley between Eddies and Tincan, on a West to SW aspect. Unsure of the avalanche type that the cornice fall likely triggered, but the debris pile was fairly wide - see photo below.

Several recent glide debris piles could also be seen up this valley on a SW aspect of Eddies.

Small chunks of cornice had recently (past few days?) fallen from larger cornices over the Eddies headwall. On the cornice sizing scale, these chunks were about the size of a little tykes cozy coupe. The bulk of the cornice remained intact and above the slope. Similar activity could be seen during patches of light over on Wolverine.

Glide avalanches and wet loose slides on Seattle Ridge (as previously reported)... nothing new today through 4 PM.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Broken to overcast skies, starting to lighten up a little when we left at 4 PM.
Occasional light winds from the south or north above 2000'
WARM. 40s at the car, and probably right around 30 at our high point (2500')

Snow surface

In the trees, the trail - where it had been packed down - was firm, but off trail a few inches of wet large melt freeze grains sat on a supportable crust.

From 1000' - 2000' the top foot of the snow was moist, with a thin wet layer/light dusting of snow from the past two days.
From 2000' - 2500', the surface snow was moist, even on northerlies, but a lot less dense than the 'hot pow' down low.
Ski penetration of 1-3" along the entire route.

There was no noticeable surface difference by aspect on northerly to southwest facing features we travelled on, and only elevation seemed to produce variation here... though a breakable crust could be felt ~3" down on small SW features while descending. No real sun on slopes until we started leaving at 4 PM.

Recent winds didn't produce any slabs on our route, though the trace of new snow plus winds did partly fill in old tracks. That said, old tracks were still visible on Eddies headwall, and at places which often see substantial winds just at treeline.


No formal stability tests.
