The webcam is back up and running, and our tech wizards are currently working on getting the images to auto-populate our website. Keep checking in the next few days, it should be back soon!!!
Observation: Turnagain
Location: Sunburst
Took a walk up to the weather station on Sunburst to fix the weather station on the ridge, which gave us a great view of the library during the hottest part of the day. We skied the south face under the weather station back to the car and had some high quality turns.

Observer Comments
Multiple loose snow avalanches in the Library. Roller balls were initiating naturally and off ski tracks on South facing slopes on Sunburst.
Weather
The temperature inversion created warmer conditions at mid to upper elevations. Not to mention the lack of cloud cover and calm breeze made for a beach-like day on Turnagain pass.
Snow surface
We had a later start, around noon, and at this point the snow surface was showing only minor signs of warming. Walking up through the valley between Sunburst and Magnum we saw pockets of small roller balls initiating off of ski tracks and rock bands; this was a result of the warming that occurred the day before.
On the ridge we got a great look at the Library where, on these steep southerly slopes, it was clear that the direct sunlight and heat inversion was initiating loose snow avalanches that ran to the bottom of the valley. Throughout our time working with the weather station on the ridge the sun really started to have an effect on this terrain and more and more small wet loose avalanches ran. The largest occurred at the end of the day and edged on being what we estimated a size D2.
Snowpack
Because our major concern for the day was surface snow warming and setting up the camera on the weather station we did not dig any pits today. We were however able to successfully set up the web camera so now it's possible to get a view of Seattle ridge and a small piece of the Magnum ridgeline in real time.
Comparisons of the Library about 2 hours apart. The red circles represent new small wet loose avalanches.

The webcam is working again and we should have these images auto-populating on our webpage in the next few days. Stay tuned! Photo of the sunset at 6:57 p.m. 03.06.2023
