Walking towards true Flagstaff we noticed a crown just to the north of the peak. Remaining hang fire was minimal so we traced the crown for about 400' before finding the edge of the slide. It slid to the ground as well, crown varying in size, but as big as 4' in spots. Looked to run near the end of the storm cycle naturally, as there was a few inches of snow on bed surface. We rode bed surface/rocks/debris into the basin and exited days via BCC.
