East and NE aspects of Alexander/Porter ridgeline presented multiple natural slides most likely occurring Thursday evening (1/17). While all of these stayed laterally confined to the slope's minor concavities, this storm slab activity was influenced by the strong pre-frontal SW winds leading into the Thursday's cold front.
Much of the debris I could make out stopped in the slope change lower in the bowl but one slide (photo 1) had debris visible down in the small conifers of the runout (Photo 3).
The wind-effect, aspect, and elevation are very similar to the adjacent Davis Gulch avalanche that Tom Diegel's party observed yesterday.
