Yellowstone Ski Tours
Protected meadow BTL
Experienced 3-4 good collapses today, presumably on that layer of buried surface hoar that was discovered to be approximately 60cms below the snow surface.
Above about 9900', the westerly aspects were quite wind effected from the Dec. 27,28th event.
No collapsing, despite a thin/ faceted snowpack and lots of trailbreaking.
Pit located in wind protected meadow just below the ridge line.
Experienced many large, thundering collapses today. I think one could have easily triggered a slab avalanche on anything steeper than about 35 degrees, in this lower/ mid elevation terrain today.
No collapsing nor much cracking, nor any recent avalanches observed despite 1.5 inches of SWE in the last 48hrs (low to moderate visibility).
Very deep trail breaking, localized collapsing. Not much wind effect. Location was in an area of burned trees from the 1988 fire season.
