Panorama of a pigtail road in the Black Hills. These roads allow for large elevation drops in confined spaces, perfect for the mountains. Before the tourist season really starts, Iron Mountain Road is a quiet place, perfect for a drive to enjoy the scenery. This scene shows the sweep of the road leading to the curve, with some distortion from the wide panorama projection.
