General Observations

Near Glacier Creek: 1953', S aspect, 35 degree slope. 140cm snowpack depth, cloudy skies, no wind. Three distinct thin rain crust layers observed in top 10cm, rest of snowpack below was solid and did not break under compression tests. Several point-release natural slides were visible at higher elevation (2500'+) and 45 degree+ slope angles. Pit GPS location: N 59 32.134 W…

Lutak Zone: Spied 2 recent natural slab avalanches across the inlet on Halutu Ridge, estimated to have run in the last 24 hours. Both on SW aspect at ~2500 ft, mid slope. Size 2, looks like wind slab in terrain cross loaded by the North winds. 35-40 degree start zone, roughly 50mx50m slabs.  The snow surface is a mixed bag of facets,…

Lutak Zone: 2,700' N-aspect air temp -14C sunny skies no wind snowpack 130cm. Three distinct crust layers in the upper snowpack from 1F to P hardness. Facets are sandwiched between these crusts. Results from our pit were ECTP7 down 15cm on a weak faceted layer with another slab supporting it from below. Eventually, that slab also propagated at ECTP23 down 35cm.…

Lutak Zone: Clear skies, moderate NW winds on ridgetops. Traveled on a large variety of aspects and elevations today. Ski/boot penitration 0-10cm max. Good stability, hard/crusty ski conditions, best between 2000-3000ft. No danger signs, no whumphs, no cracking, little in the way of fresh wind slab, though we could see some building on the highest South-ish aspects. Pole…

Lutak Zone: 3,000' NE-aspect air temp -7C overcast moderate NW wind snowpack 108cm. Stout crust from this last storm in the upper 10cm of the snowpack. This supportive layer is difficult to kick into with a slick rime ice surface. Hard failures down 30cm below a 2cm rain crust on CT19&23 SC, ECTN30. Down 98-100cm 4F melt-freeze facets with refrozen…

Discovered the facet crust combo 80cm down where a 2cm pencil hard rain crust sits over 5cm of loose 2mm facets. Compression tests were easy with CT9&10 down 80cm sudden collapse fracture characteristics. The crust does the job of supporting the…

General Observations

Pass Zone around 3 mile: Great snow conditions. 10-15cm of new snow fell yesterday and bonded well with the existing snow surface. As we broke treeline, we found evidence of a past S wind event that deposited thin wind slabs on northerly and westerly aspects. At and below treeline we found a snowpack that got more cohesive with depth…

Observed D3 natural avalanche from the last storm (around 4-5 days old), on cross-loaded west aspect near 4500ft. Ran around 4000 vertical feet through channeled gullies to hit the valley floor.

General Observations

Lower elevations on the US side were calm, but the rest of the pass was seeing 40-50 kmh winds. Lots of wind slab formation on various aspects. We saw one size 2 or 3 natural, slab avalanche on a west aspect on Three Guardsmen, which looked to have occurred recently. Full ob here:https://www.avalanche.ca/map?panel=mountain-information-network-submissions/9b12c2f2-eafb-43bd-aebe-d9958ab97a8e

General Observations

5-mile creek area: New storm snow is right-side up and appears to be well bonded. As we ventured above treeline however, felt some areas of slabby  wind-affected snow. Also observed notable hollowness/punchy-ness about 1 meter deep, apparently old facets above the old rain crust. Stability felt good in many areas below treeline but we were…

Snowpack was overall saturated and rounding. At the ground were hard frozen melt forms. Didn't perform any…

Great snow at Three Guardsman on Saturday. Skied Northwest aspect (facing the highway). Dug hasty pit near the top of the first pitch. 1 meter +/- deep, top 5 cm sheared when isolating the back of the column. The rest of the pack is consolidated till it weakens at the very bottom. No results with…

Windpacked powder boot pen ~70cm and ski pen ~20cm with evidence of wind scouring/loading on N-aspect 3,000-3,7000ft. Snowpack depth varied up to 120cm with new snow between 65-75cm. At 13:30 temps were -11C air, -14C surface, -11C 20cm, calm winds and clear skies. 5cm of depth hoar around rocks and at the bottom of the snowpack,…

Great snow at the pass. Recorded 3 natural slab avalanches on a variety of aspects, although confined to steep cross loaded aspects. Guessing they ran during the precip event on the 26th. In sheltered valleys surface hoar is growing tall, elsewhere the new snow is faceting near the surface. Quick pit revealed some easy shears…

Sunny Bunny zone: Coverage is improving, especially through the willows where skiing was possible both from and to the car. We found surprisingly good snow through most aspects and elevations, mostly made possible by 6-10cm of wind buffed, recycled powder (near surface facets). Snowpack depth ranged from 25-120cm. Deepest snow is found along sheltered north…

Weakness in the thin surface layers (top 5-10cm) failed easily. Below that, well-bonded mid pack all the way to the ground, consisting of a series of crusts and small-grained rounding facets.
