Hike up USA bowl this morning. 9:15am Had a peek over to North facing S monitor near Katie's to see if anything was going on. No one to be seen and sustained 20mph westerly wind. Found a spot not corniced to jump on and intentionally triggered a wind slab below: 150' wide up to 1' deep. Watched as a small side slope sympathetically slid 100' away from bigger slab. Turned around and had a great day turning laps in USA Bowl: 6-8" not wind affected.
