Gros Ventre river - Flowing from the calm waters of Slide Lake the Gros Ventre River tumbles down to the valley floor through debris deposited from the Gros Ventre Slide. This geologically young section of the river has beautiful scenery and is full of sharp rocks. At lower levels, it offers great technical Class III boulder dodging and eddy hopping. When the water is high it offers stomping big water, Class IV boating. At levels of four feet and above good eddies are hard to come by - hang on and enjoy the ride. View the river on the drive up from a paved turn out about a mile before the put-in.
