Avalanche from south facing slope on Tryst lake ski out

One of the large south slopes from tent ridge facing the ski out gulley from Tryst lake avalanched between 10am and 2pm today. Our group estimated it as a size 2.5. It looked to be solar triggered from a thin rocky outcropping. Bases on a crown line lower down, and large planer blocks in the debris pile, we assumed it stepped down to the Deep Persistent Layer.
