Comments
Multiple remotely (possibly natural) triggered slides noticed today on the way up George's, including one just off main trail 1/4 mile past Donut Falls trailhead signs (first pic). All were East to NorthEast facing, on steeper slopes, just below rollovers. The slide in the first pic is from just above the main Cardiff trail and looked to be human triggered (some plastic sled marks and foot steps just to side of slide and steps going towards slide that disappear (no noticeable burial/extraction, probably a surprise). The last photo is a few feet to side of skin track 100 feet below 10k' ridge line and looked to be remotely triggered from the skin track (some cracking noticed right to skin track). Others appear to be remotely triggered from skin/skier tracks about 50 or so feet away. No other noticeable slides on untouched upper pitches of similar steepness with similar rollovers. Overall, snow in lower angle terrain felt stable and not horribly wind affected, with some density change, even high up by ridgeline out of tree protection.
