John Wesley Powell River History Museum
Learn what it was like to travel down the Green and Colorado Rivers in the 1800s in wooden boats. A series of displays tracks the Powell Party's arduous, dangerous 1869 journey, and visitors can watch the award-winning film Journey Into the Unknown for a cinematic taste of the white-water adventure. The center also houses the River Runner's Hall of Fame, a tribute to those who have followed in Powell's wake. River-theme art occupies a gallery, and there's a dinosaur exhibit on the lower level.
