Avalanche: Turnagain
Location: Goldpan
Skied up Bertha creek to the lower slopes of Goldpan. We chose this spot to see if the persistent weak layer that was so active on Seattle yesterday was also reactive on the skiers side. We found a lot of avalanche activity from the past few days with some very wide propagation and crowns that were 3-6′ deep.
Avalanche Details
Lots of recent avalanche activity in this area. Elevations ranged from 2500 - 4000'. Likely released with the large wind event after the quick storm on Tuesday night into Wednesday morning. Largest crown was on the SW aspect of Cornbiscuit at about 3000'. Propagated across multiple gully features and sent debris way out into the flats. Another large crown that we investigated was on the small slope at the base of the Goldpan bowls. This was 3-6' deep and 750 - 1000' wide.
At upper elevations in Goldpan there were several deep and wide avalanches that we could only see the crowns. There were also several that looked shallower and were at higher elevation closer to the ridgeline.
Weather
Cold temps at the parking lot, but otherwise a beautiful day with calm to light winds and clear skies.
Snow surface
Large surface hoar on the surface up to our high point at about 3000' with some weak near surface facets underneath.
Snowpack
We did not dig any pits due to a short field day and our interest in looking at one of the recent avalanches. Based on the one we looked at I think most of the larger avalanches in this area released on the facets above the Thanksgiving melt freeze crust. There were several that were shallower at upper elevation in Goldpan that may have been on the interface between the Christmas and New Years storm layers.
Skinning across the debris a large natural avalanche on the SW aspect of Cornbiscuit that started around 3000' and propagated across several gullies.
Partially filled in crown on the N ascpect of Lipps at 2800'.
Recent avalanches in a lot of the steep terrain in upper Goldpan from 3500 - 4000'.

Andrew skiing down in front of the avalanche that we investigated. It was 5.5' deep on the left edge.
Large surface hoar from the parking lot up to our high point at 3000'. This was sitting on to of some weak faceted snow.
