Snow Profile Comments
Profile from bench above avalanche where I triggered a collapse and cracking
Comments
-Winds drifted the fresh snow into stiff drifts, some a couple feet deep.
-I triggered several fairly large audible collapses or "whumpfs" in low angled terrain and around rock outcrops. I noticed thin shooting cracks, sometimes 50 to 80 feet away from where I triggered the collapse.
-ECTP 11 in my snowpit in Miller Flats.
