A significant Widespread Soft Slab Avalanche Cycle appeared to occur between 1230 and 1400 on Slopes with N, NW, W and SW aspects, having Storm Slab Avalanches running fairly Long and piling up debris 2 to 3 feet deep in the bigger and more confined paths.
All of the Steep Terrain from the West Facing Boundary Area off Millicent wrapping around past Stupid Chute and to Old Reliable ran during this Widespread Cycle. Obscured Skies prevented any visibility and efforts to see any terrain outside of this small area, yet Brighton Patrol reported similar activity. This Reactive Sensitivity continued to be an issue throughout the day with Slope Cuts and Test Slopes having Propagation Propensity; and even on our exit at 1730 we were initiating avalanches very easily. At this point in time slides were up to 12 inches deep even in protected areas that were not receiving any signs of Wind Transport and or Loading. See video of Reactivity.
