Cascadilla

I visited the Cascadilla drainage to catalog recent avalanche activity associated with the Atmospheric River event from February 20 and 21. 

• Most every avalanche path in this drainage slid during the storm. Three paths ran as hard slabs and produced D3 debris at the mid and upper elevations.
• Twelve mid-elevation paths produced D2 soft slab debris which terminated in the valley floor. 
• 10-15 smaller soft slab slides were noted in cross-loaded convex terrain features between 5000 and 5500 feet. 
• Avalanche crowns ranged in elevation from around 5000 to 6600 feet and were on NW-NE-SE aspects.
• The surface snow, which was cold-smoke quality yesterday, had warmed and densified but was still in good shape.
