Today we toured outside of Snowbowl ski area in the Rattlesnake Wilderness, we rapidly stepped back in our decision making and chose more conservative terrain due to observations made.
We observed:
• Shooting cracks on the east and north aspects, in both wind-loaded and protected trees
• A small possible natural avalanche on a north accept, 7800ft., R1-D1.5, approximately 2-3 feet in depth and 50 feet wide
• Propagation in extended column tests.
• Sudden planar breaks in column tests.
• Faceting throughout the snow back in locations with less than 40 inches (100cm) of snowpack
