Avalanche Details

Multiple slides triggered by explosives and ski cuts. All aspects and elevations were producing slides to some degree or another. Mid-mountain produced the most significant slides observed today. Crown depths varied from just a couple inches to around 24 inches deep or even deeper. Slides were happening on different layers, some on layers within the recent storm snow, some on layers above the rime crust from yesterday, and a few on steep angle terrain were producing slides all the way down to the new years crust. Slide paths were rapidly refilling. Some ski cuts produced bigger slides than explosives did, and vice versa. Dense wind slabs on N, NW aspects. While moving around, you could feel and hear whumphing and shooting cracks going out about 3 -5 feet in front of you. This is a complex snowpack with the potential to release large avalanches.
