Folly Lake (17 km from campground)
Folly Lake is a spring-fed lake of more than 200 surface acres. It is one mile long and a half of a mile wide. Folly Lake formed 10,000 years ago when melting waters from glaciers dammed up both ends of an ancient mountain pass with rock debris. Today the dams and a quarry that nearly surrounds the lake are an available source of gravel and rock for the construction of roads.
