The site was designated in 1967 by the Wisconsin Department of Natural Resources to protect the bog landscapes of the region. This early conservation effort recognized the importance of these rare ecosystems before wetland protection became widespread.
The preservation of this wetland demonstrates Wisconsin's commitment to protecting natural environments that support native species and ecological diversity.
Access is via an unpaved road from US Highway 51, which circles the northern and eastern sections. Visitors should bring appropriate footwear for wet and soft terrain.
The area supports rare plant species including state-endangered bog rush and three orchid varieties. These specialized plants thrive only under the specific conditions of this bog ecosystem.
