Natural avalanche at bacon rind

Date
Activity
Skiing

We were descending through the the trees off bacon rind when we skied upon a natural avalanche that appeared to be from today. The slide began at the top of a small clearing in the woods and went down through the trees below. However, we could not see how far down it went. The crown was roughly 3-4 feet deep and propagated about a hundred feet or so. This was on the eastern facing aspect of bacon rind just south of the normal ascent trail.

Notes

From a phone call:

A rider saw a large avalanche in one of the bowls around the corner of Lionhead avalanched. It likely occurred on Friday, March 1. There were holes dug in the snow indicating a buried person or sled. This is the same slope that killed a 19 year old from MN on December 28, 2006. They conducted a beacon search on the debris to make sure no one was buried.
