Observed 2 relatively small slab pieces in North facing American Fork today that likely occurred on 1/2 during the height of PI (precipitation intensity) , one in the Outhouse area of Mary Ellen and one down around 8800' lower toward the gut of AF. The geometry and shorter-running nature are similar to other slides in the aspect/area from that event.

Trigger likely natural if they did indeed occur during the storm but based on snowmobile traffic in the area may have possibly been triggered in the following days by riders.
