From what My wife is saying there is "a lot" of wood. She showed a friend z gorge down to just shy of gun shot when she was down there. It has only come down since then, so I can't imagine it's any better now than then.
Never tried cleaning mid season before, may or may not be worth it, but I'm up for trying. I work in Breck, and will be leaving by noon... if more saws would be handy earlier I can give someone directions to my place, got a stihl 440 with a 25" bar there, the reach it has is nice for river work.
