We are in the north of the swan range today. Experienced many human triggers avalanches, no natural slides. Everything was propagating and running on the rain crust 12-18" deep. There was a very definitive two layers on top of the crust one about 6" siting on about an 8" layer almost always went together. Fracturing and propagation was very common but the loosely packed layers didn't run very far. Before stopping only one ran out to the flat about 250 feet.
More specifically we were south of six mile mountain and north of trinkus lake. Slides got worse as the day went on and were most common on convex break overs
