It sounds like something I need on my shelf but i'll download the e book to the laptop anyway.
There are a couple videos around.
Unfortunately the govt flooded it. We were the last group to go without portage of the dam site. The amazing gorge that housed big grand canyon style whitewater, jungles so thick you couldnt see ten feet in, massive walls jutting straight out of the river, all the different monkeys swinging in the trees, baboons throwin shit at you, crocs dippin below the muddy surface, hippos false charging you, leopards chillin on the bank and more wildlife than could be imagined is 700 ft under water now. It is unclear what has happened to the dozen or so subsistence farming tribes like the bumi, bode, mursi, and hamar that counted on the floods to fertilize the banks. A damn shame, what an amazing place.
