Observer Comments

We saw a couple avalanches that looked like they ran during the storm cycle. Most were on the east face of Seattle Ridge. We also saw one on the SW side of Shark's Fin. It looked like it was a wind loaded area that ran with the new storm snow. We were too far away to determine crown size, but it looked to be D2 and ran about 500'. We could also see some cornice chunks that had fallen and triggered small sluffs/soft slabs (D1) off the SW side of the summit ridge on Eddies.

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

The day started out sunny and relatively warm. The new snow that was in the sun was warming and thickening, especially at lower elevations. Around 2:00 we started to have intermittent cloud cover that continued to increase throughout the afternoon. Winds also picked up throughout the afternoon.

Snow surface

Down low consisted of wet snow underneath a breakable crust with a few inches of light fluffy snow on top. The crust disappeared around 1700' but was fun to ski down to around 1300'. Above that was mostly light snow with some isolated wind crusts and slabs.


We dug a pit around 2100' on a NW aspect to check out the storm snow from the last few days. We dug down to what we think was the old snow surface from before the storm cycle. It was around 110cm down. It seemed like the spot where we dug had experienced some scouring during the storm. Pit profile is attached. Overall the storm snow seemed to be bonding to the old surface. Our only significant result was an ECTN23 55cm down at an interface within the new snow. It seemed like the bottom of a wind slab that had formed during the snow.
