McCormick

County: Marquette

Forest: Ottawa

District: Kenton

Established: 1971

Acres: 3675

Description: This RNA features mature stands dominated by sugar maple (Acer saccharum). The topography and soils are distinctly varied. No cutting has occurred in the RNA for more than 80 years. Several state Listed species are present within the RNA: including the state threatened sandwort (Arenaria macrophylla), and three state special concern species male fern (Dryopteris filix-mas), blue wild rye (Elymus glaucus), and rock-bracke (Cryptogramma stelleri).

Ecological Information

Physical and Climatic Conditions:

Nearest weather station, with distance and direction from RNA: The nearest station is located at Herman, Michigan, 19 miles (30.4 km) west of the RNA and on the same divide. This station should provide the best available record of the climate in the RNA. Three other stations within the general area which might also provide information are the Champion, Alberta Park and Big Bay stations.

Annual precipitation (type, seasonal distribution) : During the months of June through August, precipitation averages 4 inches (10.1 cm) per month. From December through February, average monthly precipitation is 2 inches (5.08 cm). Yearly snowfalls up to 300 inches (762 cm) have been reported.

Maximum and minimum temperatures : Mean monthly temperatures range from 12-14 ºF during the months of January and February, and from 60-65 ºF during June-August. The recorded minimum temperature is -40 ºF, and the recorded maximum temperature has not exceeded 100 ºF.

Elevation: The elevation ranges from 1,860 feet (567 m), located on the divide between the Yellow Dog River and Lake Marquette, to 1,480 feet (451 m) at the exit of the Yellow Dog River at the northeast corner.

Geology and Soils: The western and northeastern portions of the site contain relatively flat, sandy outwash plains separated by a rugged escarpment approximately 3/8 mile wide. Surface features and soils are derived from deposits of glacial till and outwash. Much of the bedrock is gneiss. Podzolic soils dominate the area. The soil series found on this RNA include: Michigamme (Bedrock), Champion (weakly developed fragipan), Karlin (Textural bands), and Kalkaska and Pence (no obstruction).

Aquatic Features: The main and west branch of the Yellow Dog River pass through the site. The site also contains 5 1/2 miles of stream, a small lake (5 acres) and Lake Margaret (120 acres). Streamflow through part of the RNA is regulated by a dam at the outlet of Bulldog Lake.
