International Paper operates a large plant in Ticonderoga, on the edge of Lake Champlain, which makes pulp and paper from Adirondack trees, and is the sole remaining operating paper mill in the park. For nearly a century, International Paper was one of the largest private landowners in Adirondack Park, owning more than 320,000 acres in 1996. With the increased use of southern forests for pulp, and the room to make bigger and bigger plants, International Paper’s US operations moved south. It is now headquartered in Memphis.
