Quick report
A large block pulled out below me on a N facing ridgeline at 5400' around 15:30. This particular area didn't appear to be corniced, but I was still off of the edge about 4-5' when it broke. Block traveled about 40' before it was stopped by a large group of trees. The block was about 10'x10'x5', and ripped out a 4"-5" diameter tree in it's path.
