Big Island Lake Wilderness

Twenty-three lakes, ranging in size from 5 to 149 acres are found in this Wilderness where ducks, loons, and great blue herons are often seen feeding. Bald eagles are occasional visitors, and sandhill cranes frequent the open upland in the area's northern section. Hardwoods (maple, white birch, beech, and quaking aspen) dominate the uplands which are inhabited by black bears, pine martens, bobcats, raccoons, porcupines, and chipmunks. Hemlock, spruce, and balsam fir are found in the low wetlands along streams and bogs. Logged between the 1890s and 1930s, old stumps can be seen scattered among second-growth, but the area has recovered much of its appearance of the earlier forest, with large trees and a closed canopy overhead.
