Section 8 of the Lewis & Clark Bicycle Trail traces the eastbound path Captain Clark explored along the Yellowstone River in 1806. Services are limited in eastern Montana. Much of this map section is either on I-90 or its frontage roads. From Three Forks eastward you'll cross several Gallatin River tributaries which flow into the Missouri River. The terrain on this section is rolling; you'll have great views of the Yellowstone River and Big Sky country. Three Forks, MT, to Glendive, MT (417 mi.)
