Hancock and Black Canyon

#1
Accessing to Black Canyon (NF) has always been a bit of mystery to me. With my Hancock Permit I have scouted what I think is an access point to the Canyon, but always hit a wall of brambles and thicket. With the potential for a dam going in, I definitely want to scout it out and perhaps become more active in protesting the dam.

Any secrets on how to get into Black Canyon would be great. I know it can't be that big a deal, but for me this has been a multi-year quest!
