The Ontonagon River ( ON-tə-NAH-gən) is a river flowing to Lake Superior on the western Upper Peninsula of Michigan in the United States. The main stem of the river is 25 miles (40 km) long and is formed by a confluence of several longer branches, portions of which have been collectively designated as a National Wild and Scenic River. Several waterfalls occur on the river including Agate Falls and Bond Falls. Source: Wikipedia
