South Fork Fortymile River
The Fortymile River is a clear water stream whose six main forks and their tributaries flow out of the Yukon-Tanana Uplands east of the Mertie Mountains and north of the Tanana State Forest. It is a major tributary of the Yukon River. Road-accessible boat launch sites and bush strips in the upper reaches allow trips varying from one day to two weeks. The main Fortymile offers a great way to see the differing landscapes of the interior of Alaska in a two-day float, from incised canyons to the wide-open Yukon Valley. For More Information Visit:
