I know we should not have been on the PCT below the big waterfall, but we accidentally ended up in the avi zone because the CCT was not tracked out correctly. We were careful as we crossed the zone, no whomping, but minor rollers triggered by us. No snow separation occurred by our steps. The waterfall did a huge ice release right above us though and it was terrifying as we waited to see if an avi would be triggered. This was at 1:30 pm.
