Quick report

Stunner of a day to be out with soft snow and no wind. Sun kept trying to truly poke out and bring on a loose wet cycle, but patches of blue sky were as far as it got. No slab activity today but loose dries, natural and skier triggered, were running far. No loose wet observed, even on SE aspects above Great Bear creek that stayed in a sunny hole for a few hours (although probably too far away to see if they were there).
