Touchy graupels on MacPherson

Lower angle / elevation skied well and without signs of instability, but that immediately changed as we got up to higher and steeper slopes. Lots of sluffing in steeper terrain 35 degrees or more around 1400m - 1500m Many Natural and skier triggered size 1 Mostly running on a touchy layer of graupel under the storm snow. This was present through all the runs we crossed. Evidence of size 2 from yesterday.
