Widespread Avalanche Cycle in the Brighton Perimeter as noted by all Instructors and Groups during the UAC Backcountrty 101. Both Naturals and Human Triggered Slides were reported. A Natural Cycle appeared to occur in the Millicent Bowl some time just after noon. Multiple slopes had releases of up to 12 inches deep with the majority 8 inches deep. The Millicent Bowl has yet to be opened this season and is un-skied terrain. In addition multiple Human Triggered slides were reported with remote triggering initiating each occurrence. Slides were easily triggered just by just approaching steep roll overs and or ridgeline break-overs from a safe distances away from the steep terrain. The majority of these slides were similar in depth to the Natural activity observed in the Millicent Bowl area with depths of slides ranging from 8 inches to 10 inches. Slides were running to transitions and were all new snow slides that appeared to be at the interface of the latest impulse that initiated at 0600 on Saturday the 10th.
