According to Dan Johnson with Dinosaur National Monument, the 34-year-old man from Denver was on a 16-member private rafting trip when a raft carrying four people flipped near Triplet Falls.

“After running the rapid, four members of the party hiked back upstream to run a section of the rapid known as the Birth Canal with a 9-foot paddle raft. The group made it through the Birth Canal, but hit a rock shortly below, and the raft flipped, dumping all four occupants into the river,” Johnson said in a statement.
