Quick report
- Cracking
- specific
Also observed a new rime/freezing mixed precipitation crust forming on snow surfaces on all aspects near and above treeline in the Timberline area. New, soft wind slabs in slightly wind sheltered lee terrain were touchy and relatively small, but actively growing. Generally 6-8” thick at 9:30 this morning. Stiffer new wind slabs also observed on lee slopes with more direct wind loading. These were stubborn, but would crack under skis if undercut by a skin track. While less likely to human trigger, they could produce a larger avalanche. New wind slabs were generally stiffer at higher elevations, 7,000’, compared the 6,000’ treeline area. All new wind slabs shared a layer of very low density snow as a weak layer at these elevations, 6,000-7,000’. This weak layer is likely the snow that fell yesterday on minimal wind.
