Natural Features and SceneryThe campground occupies rolling jack pine plains shaped by glacial activity thousands of years ago. Sandy soils support forests of jack pine that surround the lake and provide shade and privacy at individual sites. The shoreline offers a small beach marked with buoys for swimming, and the forested setting attracts white-tailed deer, bald eagles, and loons. Views across the water open up through the pines, especially at sunrise. Elevation sits at 1,191 feet.
