Spreading like fingers on a hand across the southern side of the Upper Yukon Valley, the five forks of the Fortymile River begin as nunerous small, clear headwater streams. A major tributary of the Yukon River, the Fortymile flows generally northeasterly to empty into the Yukon in Canada. The Fortymile and its tributaries drain approximately 6,600 square miles of the Yukon-Tanana Uplands. The Fortymile offers mining history, scenic country, and a road-accessible river trip. The North Fork of the Fortymile is formed by the confluence of Slate and Independence creeks, which flow from 5,000-foot mountains in the Yukon-Tanana Uplands. The North Fork flows east, then south, and after the Middle Fork empties into it, flows southeasterly to its confluence with the South Fork, for a total distance of 55 miles. Average gradient of the North Fork is 10 feet per mile.
