-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.
