Those who travel on the Mickelson Trail from the Mystic Trailhead will cross this trestle bridge that once carried passenger and iron ore trains over Castle Creek. Jon Crane has captured the beauty of summertime found "Blooming Along the Trail", including Black-eyed Susan, Beebalm and Aster. Imagine the sound of the flowing water and the bees buzzing from flower to flower as you travel deeper into the Black Hills.
