Good call, Mike - almost a textbook example. That block sure does rock back & forth! I'm going to guess that it's fairly well wedged in there, though - it sure has seen a lot of traffic. But I still wouldn't be pulling out on it!
i didn't think that block was too bad (although i DEFINITELY wasn't yarding outward like that, yikes...). i thought the pancake flake above was a bit unsettling as it was hard to not pull out a bit on it.
Well, the block fell out---fortunately not while someone was yarding on it as in this picture. The fact that it just went one day confirms that the warnings about not pulling on it were justified. Thank god no one got hurt.
Meanwhile, this photo is going to go into the Annals of How Not to Climb on Real Rock.
