Hartwick Pines State Park will host the annual Black Iron Days Festival on August 24 & 25—the largest annual gathering of blacksmiths in Michigan. Over 50 craftsmen and women will be on hand demonstrating their trade at the logging museum located at the park. The two-day event, taking place from 10am to 4pm each day, also will recreate the sights, sounds and scents of an historic sawmill cutting logs into boards. Watch woodworkers, weavers and wool spinners as they show how their crafts were done in the era before power tools. Full Moon Jam will be performing a mix of traditional and original music. The Hartwick Pines Logging Museum is a field site of the Michigan Historical Museum that interprets Michigan’s white pine logging era of 1840-1910. The event is free, however, a Recreation Passport is required for vehicles entering Hartwick Pines. For details on the program, call the park at (989) 348-7068.
