Observations

Parked at 2,400 ft on Canyon Creek Rd (mixed snow and rain). Traveled via sled to 4,800ft on Whistler Creek Rd. It was snowing hard and sticking to the trees above 2,500ft with light to no wind. Above 4,000ft winds increased to moderate and accumulation increased greatly (over 12" of new snow on the road). We skinned to 5,100ft in NTL terrain on slopes less than 30 degrees. We experienced moderate to heavy snowfall and light to moderate winds. Isolated shooting cracks and collapses while skinning in more wind-affected terrain, we did not experience either while skiing and snowboarding downhill. The new snow was right side up and seemed to be bonding well to the old snow surface. Conditions were fun and deep!
It was still snowing heavily on our way back to the truck, accumulation was still much less below 4,000ft. Snowing heavily at the truck but still not accumulating.
