[MCR] South coast avalanche activity

New Avalanche Activity:
I have been doing long mountain bike rides around the Squamish Trails yesterday and today.  Daytime highs of 24 degrees.
Saturday: Large slab avalanche  crown(fracture) line was visible on Mt. Thyestes(across the Squamish River at the eastern end of the Tantalus Range), East aspect at 1500 M, treeline bowl feature.  Approx. size 2
Sunday:  Large slab avalanche crown(fracture) line was visible on Mt Murchison / Mt. Lapworth Bowl( across the Squamish River west of Squamish).  East aspect 2000 M, alpine Ridge feature.  Approx. Size 2.5 
It looked like the crown lines were a couple of meters deep viewed from 10 km away.  There were no rocks or ground visible in the bed surface.  The debris was not visible from my locations.
