Since becoming the first nonmotorized outfitter to run the Colorado River in 1969, O.A.R.S. has dominated the 200-mile stretch of whitewater that roars through the Grand Canyon. Today its guides also hit every other major river in the western U.S. and Canada—plus an increasing number in South America and the South Pacific.
