Region: East Slopes Central - Lake Chelan to South of I-90

Area Description: Spider glacier area

Route Description: Phelps creek TH to spider glacier.

Weather: Scattered clouds.

Snowpack: Protected areas had a surprising amount of interface between the previous two storm cycles. We did find a buried crust in some but it was not consistent. Mostly baseless early season snowpack between 8-15”. Lots of sharks in the waters.

Avalanches: Some cliff bands had slid, as expected. No obvious slide evidence on any other slopes.

Region: West Slopes North - Canadian Border to Skagit River

Area Description: Heliotrope Ridge

Route Description: North side

Weather: Mostly sunny, very little wind when we were there

Snowpack: Very wind and rain-affected; grassy slopes in area didn't have much snow, snow up to the ridge was crust, both supportable and trap-style were encountered... Lots of people taking one lap and calling it, but I didn't think it was thaaat bad..

Avalanches: None observed

Region: West Slopes South - South of I-90 to Columbia River

Observation by Billy Bob

Area Description: Leuthold couloir

Avalanches: A party climbing leuthold couloir triggered an avalanche and was carried through the hourglass onto the Reid glacier, suffering minimal injuries. The party was evacuated by PMR and the Crag Rats. Be safe out there. https://www.facebook.com/124346117630344/posts/while-our-teams-were-finishing-up-the-first-mission-of-the-weekend-we-got-the-ca/3199130490151876/

Region: West Slopes Central - Skagit River to South of I-90

Area Description: Mountain loop area

Route Description: Sunset mine trail, through headlee pass to vesper peak

Weather: Fog with very light precipitation

Snowpack: Consolidated spring snow with layer of moist, freshly fallen powder of top, varying in the range of 1-3 inches in Wirtz basin to 10+ inches on the east slopes of vesper.

Avalanches: Observed two large cornice falls from Sperry peak around 08:45 while ascending through Wirtz basin, which landed on high angle (>50 degree) snow slopes on the eastern flank of Sperry, but did not trigger avalanches. In the basin around lake Elan, debris of recent natural loose avalanches was abundant on all aspects, and large glide slabs loomed above the wolf/sperry col (see photo). While descending from Vesper (13:00), we triggered numerous pinwheels. Descending from Headlee pass at 13:45 (east aspect, 45 degrees), we triggered a D1 loose wet slide that ran ~150 ft but entrained only the ~3 inch top layer of freshly fallen snow; no one was caught in the sluff. Debris was also evident from a slightly larger D1.5 loose wet slide below Headlee pass, which was triggered by a skier prior to our descent; again no one was caught in the slide.

Region: Snoqualmie Pass
Observation by Charlie Hagedorn

Area Description: Snoqualmie Pass

Route Description: From pass level to above 5k. Selected a quiet route for a quiet day out, but home again today on this holiday weekend. Traveled with snowshoes for versatility.

Weather: Overcast, clearing slightly in afternoon.

Snowpack: ~5cm of new snow above ~4k. Trees were plastered from westerly pass flow during the storm, becoming a steady shower of slush from above through the day. Below the heavy new snow, upper snowpack was wet; perhaps the storm started with rain. New/old bond was poor. I suspect that ski cuts on slopes 35-40 degrees would have produced shallow but heavy loose wet results. Extrapolating upward to higher elevations, the volcanoes may have required careful travel. Boots, snowshoes, and microspikes were all useful at various locations through the day. If we'd been on skis, ski crampons would have been welcome at times. Skiable snow above ~4.2k on shaded slopes, but it is going fast and quality was mediocre. Think schmoo.

Avalanches: None seen. Beautiful pinwheels to 0.5m.
