Avalanche on Deep Creek / Pole Creek Ridge

Our group of six was travelling along the top of the Deep Creek/Pole Creek ridge moving west. Winds were approximately 30mph gusting to 50-60mph. Along the ridge we saw shooting cracks and other evidence of instability so a route off to the north seemed unsafe and highly unlikely. We re-grouped in a flat spot away from the ridge to transition (39.24532, -120.23846) and safely ski back down our skintrack. At this point one of the members of our group noticed that an avalanche had been remotely triggered downhill from us to the north . It was approximately 50m wide and ran approximately 25m. We estimated it at R2, D2. We safely descended our skin track back down to the trailhead. On our descent we observed rapid warming with rain back at the trailhead.
