The Bob Marshall Wildlands Complex is a proposed public/private conservation area in northwest Adirondack Park. It is centered around the biggest block (50,000 acres) of unlogged forest in the Northeast. This could become a half-million-acre nearly road-free area, providing safe habitat for the full range of native species, including extirpated apex predators like Wolf and Puma. It includes scores of lakes, ponds, and rivers, including the fabled Oswegatchie River.
