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 sinkhole is slowly continuing to collapse and the surface is sliding toward the sinkhole. 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 flags.
