Text Box:  As can be seen here, collapse of a sink is also a localized natural hazard! The Stevens Twin Sinks Preserve is a 30 acre parcel owned by the Michigan Karst Conservancy in Alpena County. It was purchased in 1993 with gifts from William and Archie Stevens and other members and friends of the MKC. The Preserve surrounds two sinkholes separated by a fragile saddle-ridge, each about 200 feet in diameter and 85 feet deep, which give the Preserve its "twin sinks" name. An interpretive nature trail that visits the rims of these sinkholes and other karst and natural features of interest is currently being developed.  Other sinkholes in the area are on private property and may not be visited by the public. The Stevens Twin Sinks Preserve is the only sinkhole site open to the public in this area. All nature lovers trust that the public will treat the sinkholes and other features to help preserve them for public interest and enjoyment now and in the future. Quite recently the Bruski Sink across Leer Road (photo below) was donated to the Conservancy and made part of the Preserve. This sinkhole has been used for illegal dumping of trash for many years, contributing to the contamination of groundwater in the area. The MKC plans to clean out most of the visible trash and install barriers to future dumping.
