The Big Bog sits on the southeast side of glacial Lake Agassiz, formed during the last ice age. This former lake bottom is quite flat, with occasional hills of gravel deposits or rock. As the lake drained, this area slowly filled in with wetland plants and animals. The Anishinaabe gathered blueberries, fished, and hunted game here until the late 19th century. In the 1920s and 1930s virtually all areas in the vicinity had their majestic old growth pine trees cut down as a massive logging effort swept through, but because of the swampy nature and lack of large stands of mature pines, the Big Bog area was relatively untouched. (Also see the Lost Forty in the Chippewa National Forest). Some efforts have been made to drain portions or harvest the peat, but met with little success. Scattered communities of mixed farming were relocated from some of the more remote areas during rural reform as part of the Rural Electrification Act during the 1930s and 1940s. The fishing-dependent community suffered after a disastrous fall in walleyed pike or walleye (Sander vitreus) population in both basins of Upper and Lower Red Lakes during the 1990s. In 2002 members of the Upper Red Lake Area Association pushed the idea of a new state park, soon after nearly 10,000 acres (40 km2) were classified as the Big Bog State Recreation Area.
Bog Walk
A recent addition to the Big Bog State Recreation Area is a raised boardwalk across the bog which allows visitors to explore one mile (1.6 km) into the "islands" of spruce within the bog, as well as the open wetlands. The boardwalk was designed to allow up to 37% of natural sunlight to fall through, allowing delicate bog plants to continue to grow under the walkway. Numerous signs identify aspects of the bog, including pitcher plants and an early failed attempt at draining the swamp lands. A parking pass needs to be purchased at the nature center nine miles south, on the northern side of the town of Waskish.
One of the largest peatlands remaining in the conterminous United States, illustrating a variety of geological features and plant associations, especially the dominant and rare string bog. An outstanding habitat for wildlife including endangered species.[3]
Also included in the greater Big Bog area is the Lost River Peatland, a designated Scientific and Natural Area for the state of Minnesota. It was designated in 1991. It is also an AudubonImportant Bird Area, and contains the largest number of rare plant species of any peatland in Minnesota.[5]
