The Marion River is a 4.5-mile (7.2 km) river that connects Blue Mountain Lake via Utowana Lake and Eagle Lake (the Eckford chain) to Raquette Lake in Hamilton County in the central Adirondacks. New York State has classified the Marion as a Scenic River. The Marion River Carry is a portage around the rapids in the Marion River to Utowana Lake. The carry was shortened by a dam, that raised the level of the river and then by the Marion River Carry Railroad; at 1,320 yards (1,210 m), it was the shortest standard-gauge railroad line in the United States.
