Transportation
Iron Mountain is a peak in South Dakota’s Black Hills that is notable less for its elevation than for the scenic road that crosses its summit. U.S. Route 16A was intentionally routed over the mountaintop so travelers could enjoy views toward Mount Rushmore National Memorial. Because of that design, the mountain became part of the Black Hills landscape experience, serving both as a natural feature and as a carefully planned vantage point along one of the region’s scenic drives.
