Rando is correct the upper section is amazing. We (mike g., Jessie barber, Justing T. Rob Gilcrest and myself) have the upper first decentes. The first waterfall is about 15-20ft and called bull riders only, then there is a 90 degree class v ledge hole, then the third big drop is called conveyor belt, also class v. then it mellows for a several miles with class III scattered. the main event is fun, but Mike G. and the rest of us can attest to this, be very careful. We have had some close calls. If you try to find the upper put in and do, be careful, be prepared and pack a lunch.....its a long day. but as always worth it.
