Green River Rafting through Lodore Canyon trips are filled with excitement and beautiful scenery. We will encounter 800-foot canyon walls superbly crafted by Mother Nature of Precambrian Bedrock along with exquisite vermilion rock formations. Many of its exciting whitewater rapids were named by John Wesley Powell, who first discovered the canyon in 1869. Powell’s adventures live on in the whitewater rapids he named: Disaster Falls, Triplet Falls and Hell’s Half Mile. Set aside as an American treasure in 1938 under the National Park System, the Green River through Lodore Canyon is a sanctuary for bighorn sheep, pronghorn and birds of prey. This trip is a geologists dream with rock layers from 1.1 Billion to 20 Million years old; come time-travel with us on the Green River!
