Avalanche Details

Multiple windslabs triggering throughout the hike from Flattop to Peak 3. Mostly isolated pockets (D.5) that did not want to move, probably due to friction with the ground. Biggest was on Peak 3, where the windslab did want to move on the old snow.
Not really a danger to travelers today, but definitely a sign of things to come.
