Henry Schoolcraft discovered a lake in what county?
Schoolcraft River The Schoolcraft River is a tributary of the Mississippi River, approximately 30 mi (48 km) long, in northern Minnesota in the United States. Although short, it is considered as the first major tributary of the Mississippi, since it is the first river that joins the Mississippi below its source that is nearly the same size as the Mississippi itself. The river is named after Henry Schoolcraft, who mapped the region and discovered nearby Lake Itasca as the source of the Mississippi in 1831. Its name in the Ojibwe language is "Ozaawindibe-ziibi" (Yellow-head River), named after Ozaawindib who guided Schoolcraft to the nearby "Omashkoozo-zaaga'igan" (Elk Lake), which Schoolcraft then named Lake Itasca. Prior to being named for these early explorers it had been called the "Naiwa River"
Torch Lake (Houghton County, Michigan) Torch Lake is an approximately 2700 acres lake lying mostly within Torch Lake Township with portions within Osceola and Schoolcraft townships in Houghton County in the U.S. state of Michigan. The lake is fed by the Traprock River.
