County: Forest

Forest: Nicolet

District: Eagle River

Established: 1992

Ecological Information

Physical and Climatic Conditions:

Nearest weather station, with distance and direction from RNA: The nearest weather station is the Nicolet College Weather Station just south of Rhinelander, Wisconsin, approximately 34 miles (55 km) southwest of the RNA.

Annual precipitation (type, seasonal distribution) : The mean annual precipitation is 30.6 inches (78 cm). Annual average snowfall is 56 inches (142 cm).

Maximum and minimum temperatures :The mean high temperature in July is 68 ºF, and the mean low temperature in January is 0ºF.

Elevation: The elevation at the site varies between 1690 feet (515 m) and 1720 feet (524 m).

Geology and Soils: The topography is rolling, glacial moraine. Precambrian metamorphic rocks underlie the site. These rocks are primarily mafie, metavolcanic rock with subordinate metasedimentary rock of the lower Proterzoic Era. The area is primarily upland, deep, moderately well drained soil formed in 2.5 to 3 feet of fine sandy, loam aeolian material overlying gravely sand.

Aquatic Features: There is no open water within the RNA, but it lies between Bose Lake and McKinley Lake.
