The forest was established in 1957 and covers approximately 68,000 acres in Jackson County. Trails run through woodlands and rolling terrain shaped by glaciation, with buttes, hills, knolls, ridges and pediments. Scenic overlooks and ridge views are noted features, and the event highlights fall colors.
