The South Branch Grass River and Middle Branch Grass River converge near the settlement of Degrasse, forming a landscape defined by significant water drops and remote ponds. This area of Saint Lawrence County is characterized by numerous waterfalls, including Basford Falls, Sinclair Falls, and Twin Falls, which mark the river's descent through the Adirondack foothills. To the east, the small settlement of Clarksboro sits near Twin Falls, while Camp Flat-Rock and Flat Rock Falls are located further into the interior.
