The Story
The canyon runs about 19 miles along US-14A between Spearfish and Cheyenne Crossing, its buff Pahasapa limestone the same rock unit that holds the Black Hills' famous cave systems. Much of the modern highway sits directly on the grade of a railroad abandoned after a 1933 flood. The route was formally designated both a state and a U.S. Forest Service scenic byway in 1989, and is one of the most-driven roads in the Black Hills — spectacular during Sturgis Rally week.
