| With an area of 9,672 acres, Hartwick Pines, near Grayling, is the largest state park in the Michingan's Lower Peninsula. The park's rolling hills, which are built of ancient glacial deposit, overlook the valley of the East Branch of the AuSable River, four small lakes and unique timber lands. The principal feature of this park is the 49-acre forest of Old Growth Pines which gives the park its name. This forest is a reminder of Michigan's past importance in the pine lumber industry. |
