More detailed information about the avalanche: 

On the West Mt ridge south of Lone Tree peak.  I am assuming this was triggered remotely by a sled on the road on the ridgetop.  At 1st I thought it could be a natural but decided that the location in terms of loading did not look right. I did not see any tracks on the slope but checked a map and saw there is a road there.  I also heard sleds later in the day.

I will also add other info in an ob.
