General Comments

I got a call from a friend at the Green Canyon Trailhead at around 5:30 yesterday evening.  A wet natural avalanche had occurred quite recently, stopping on the flats only feet from the road just below the parking area.

My son Liam and I didn't have far to go to check this thing out, as the toe of the debris was right near the road.

This is a good chance to check out an avalanche....  Truly the urban interface, the avalanche came down right next to freshly built snowboard jumps and buried a good number of ski and dog tracks.....  A pretty big pile of snow down here and there are much bigger piles higher up on the slope...Up there, it stacked up deeply on trees and filled in gullies.

Actually a couple avalanches started with narrow point releases in the rocks and along the ridge-line and then fanned out to encompass nearly the entire slope.
