Walk with dinosaurs, sail through a Great Lakes storm, paddle in a kayak, or snowshoe the backcountry. Whatever the season, there are always things to see and do in the Sanctuary of the Great Lakes.
Rockport State Recreation Area Sinkholes
GPS: 45.202533, -83.384076, take US-23 North, turn right on Rockport Road, the park is at the end of Rockport Rd.
Rockport is Michigan’s 100th State Park and is the first State Park where you are allowed to take a piece of it home with you. There are 13 sinkholes located at Rockport as a result of the Karst topography of the area. One of the sinkholes is over 100 feet deep and filled with water from an underground aquifer. Search for Devonian Era fossils around the sinkholes or in the abandoned 300-acre limestone quarry located on the property. Visitors are allowed to take up to 25 pounds of rock per person from the park per year. While you are here also check out the old deep port harbor, remnants of the former limestone mining operations that sat on the property.
Rugged trails loop throughout the property. Hike, bike, or bring your horse to ride the trails.
Starlite Beach is full of family fun. Sandy swimming beach, playground, splash park (coming summer 2018), picnic pavilion, indoor restrooms, and outdoor shower. Close to restaurants and lodging. Adjacent to Lee’s Mini-Golf, the oldest continuously run miniature golf course in Michigan.
Stevens Twin Sinkholes
GPS: 45.18231, -83.71981, near the corner of Leer Rd and Maple Lane Rd, approx. 20 minutes from Alpena.
Stevens Twin Sinks Preserve is a 31-acre parcel purchased in 1993 with gifts from William and Archie Stevens and other members and friends of the Michigan Karst Conservancy. In it are two sinkholes separated by a fragile saddle ridge, each sink is about 200 feet in diameter and 85 feet deep. Located across from the Bruski Sink on Leer Road near the intersection of Maple Lane Road, the Stevens Twin Sinks are a geological treat. Earth cracks are viewable at Stevens Preserve and indicate that the sink hole is slowly continuing to collapse and the surface is sliding toward the sink hole. This Preserve has two self-guided trails. One trail generally follows the perimeter of the sinkholes with a spur to the earth cracks. Another trail is found off the spur trail and takes visitors through the woods and meadows of the preserve and is marked with yellow and red flagging.
More information is available at the Alpena Visitor Welcome Center at 420 N. Second Ave, Alpena, MI 49707.
