I spent the last two days observing a truly widespread cycle of avalanche activity. I observed many dozens of very large avalanches in alpine terrain, many of which broke extremely wide and wiped out entire alpine bowls. The threat from these is very obvious and in your face.
I also observed many avalanches in gentler, less obvious avalanche terrain. Many of these were in and adjacent to popular ski terrain in the greater Galena Pass area and in similar terrain frequented by riders in the drainages above Smiley Creek.
These are the types of avalanche conditions that catch people off guard. You aren't likely to experience obvious signs of instability before triggering a very large avalanche.
Slides on shaded slopes generally seem to be failing at the 2/18 interface. Slides on solars are picking off crusts+facet combos a bit higher in the snowpack, at 2/26, 3/7, 3/9, and 3/12.
I've been mostly seeing crowns and not the extent of the debris below. The Galena Peak slide in the SW bowl ran fast and far, running all the way to where the drainages below the NW bowl and SW bowl come together. I suspect we will hear many reports of folks finding crowns and debris in places they have never seen crowns and debris.
