Description: This RNA contains an excellent example of relatively undisturbed, old-growth forest dominated by eastern hemlock (Tsuga canadensis) and yellow birch (Betula alleghaniensis). The understory composition is typical of an old, hemlock-dominated stand.
Nearest weather station, with distance and direction from RNA: The nearest weather station is in Park Falls, Wisconsin, approximately 22 miles (35.2 km) to the west, northwest of the RNA.
Annual precipitation (type, seasonal distribution) : The average annual precipitation is 33.9 inches (84.8 cm). Average snowfall is 70 inches (175 cm).
Maximum and minimum temperatures : The mean annual temperature is 40.5 ºF. The maximum summer temperature is 106 ºF. and winter minimum temperature -45ºF.
Elevation: The elevation is 1560 feet to 1590 feet (475 m to 485 m).
Geology and Soils: The topography is an excellent example of pitted glacial moraine, with numerous kettles. The area is a relatively level to rolling topography segment of a pitted outwash plain and is well drained. The soil is closest to Vilas Loamy Sand Series.
Section: Southern Superior Uplands (212J)
Subsection(s): Northern Highlands Pitted Outwash (212Jm)
Plant Communities: Quercus prinus, Quercus velutina, Sassafras albidum, Carya spp.
