Whitewater rafting in Colorado attracts enthusiasts from far and wide and The Denver Post has topped their ‘Best Whitewater Rafting Stretches’ list with rafting the Yampa and the Green River within Dinosaur National Monument. The article quotes Colorado based professional river guide Sean Sorrin as saying, “For multi-day river trips, the Gates of Ladore [section] on the Green River and the Yampa River are both outstanding, in Dinosaur National Monument, and have cultural history. The two different trips finish at the same place…The scenery for both trips is outstanding, and the geology is opposite despite both being in Dinosaur National Monument and so close together.” Sorrin also described the thrill of reading nightly to the guests from John Wesley Powell’s journal when guiding the Gates of Ladore, stating that Powell’s “descriptions and writings were detailed and poetic from his first voyage through The Great Unknown, a blank area in the United States map, that Powell was mapping.”
