Description: This RNA site contains a 42 acre shallow, softwater drainage lake, essentially undisturbed, as well as a large northern white cedar old growth (Thuja occidentalis) swamp, which is the largest of its type known in the Chequamegon National Forest. Two slow, softwater streams and the headwater portion of a third such stream are also present. A large ericade bog, a good quality northern sedge meadow, and a five acre stand of old-growth eastern white pine (Pinus strobus) are also present. Animal diversity within the site is high and includes the American bald eagle (Haliaeetus leucocephalus), Federally Threatened and State Endangered; the red-shouldered hawk (Buteo lineatus), State Threatened; and the black-backed woodpecker (Picoides arcticus), State Special Concern.
Nearest weather station, with distance and direction from RNA: The nearest weather station is in Mellen, Wisconsin, located approximately 8 miles (12.8 km) to the northeast.
Annual precipitation (type, seasonal distribution) : The mean annual precipitation is 33.9 inches (84.8 cm). Average snowfall is 85 inches (212.5 cm).
Maximum and minimum temperatures : The mean annual temperature is 39.5 ºF. The maximum summer temperature is 101 ºF. and winter minimum temperature -49 ºF.
Elevation: The RNA has an elevation of 1450 feet (435 m).
Geology and Soils: Precambian granite bedrock underlies this area. The landscape is young in geologic age and characterized by a deranged type of drainage pattern. The Soil is Tawas and Padus series.
Aquatic Features: Aquatic features include a 42 acre shallow, softwater drainage lake; two warm, slow softwater streams (3 acres), and headwaters of a third stream. The two softwater streams flow into McCarthy Lake. The lake’s outlet flows through a field of large boulders and is, to some extent, subterranean.
