Tahquamenon Falls, on the Tahquamenon River in Michigan’s northeastern Upper Peninsula, consists of Upper and Lower Falls within Tahquamenon Falls State Park. The largest waterfalls in Michigan and among the biggest in eastern North America, they are known for both their scale and their deep brown, tannin-stained water, which inspired the nickname Root Beer Falls. The Upper Falls drop about 48 feet across more than 200 feet, while the Lower Falls form five smaller cascades around an island downstream. The name is old enough to appear on a 1671 French map, and the river and falls later entered American literature and art, helping make them a major regional attraction.
