Twin Lakes Bog State Natural Area
Twin Lakes Bog State Natural Area is a Wisconsin Department of Natural Resources-designated State Natural Area featuring an intact tamarack swamp lying in a depression between two kettle lakes. The understory of the swamp has an open aspect to it, and is dominated by the ericaceous shrubs Labrador tea, bog laurel, and leatherleaf. Other common plant species found here include: wooly-fruit Sedge, twinflower, cinnamon fern, sundews and, and the notably abundant pink ladyslipper. Three small bog lakes, surrounded by quaking bog mats, are found in the interior of the swamp. Uplands surrounding the swamp are forested with second-growth hardwoods dominated by sugar maple and red oak. In 1989, the US Forest Service designated Twin Lakes Bog as a Research Natural Area.
