It is in the watershed so you can't be there. They run helicopters and all sorts of surv. I am pretty sure at one time they had homing pigeons with laser guided cameras but you would need to ask royhprum. He says he boats up there pretty regularly.

I have hiked into Lester to check out the river but I was stopped by an official before I could actually start moving down stream towards hanson.

The only person that I know who has actually done it is FranzHorner. If I remember right he said there were a few III or II drops but it was mostly a braided river up there.
