South of Buffalo Rock, the road continues along the winding course of the Snake River through rugged and picturesque terrain. Time-scarred peaks, sometimes 2,000 feet in height, rise above the tortuous course of the stream. In some places the canyon walls are said to be as steep as those of the Grand Canyon of Colorado. Fantastically contoured rocks present a variety of rich colorings under varying conditions of light and shade. The rapids are located just downriver from Captain John Creek. A ferry crossing used to exist near the creek entry to the Snake River, providing access to the east for overland travel up to Craig Mountain.
