The fourth section of the Lewis & Clark Bicycle Trail begins in Dickinson, North Dakota. The route follows the I-94 corridor, alternating between the freeway and parallel county roads. In eastern Montana it stays south of the Missouri River. This part of Fort Peck Lake/Missouri River carries many additional designations: the Charles M. Russell National Wildlife Refuge, the Upper Missouri National Wild and Scenic River and, most recently, the Upper Missouri River Breaks National Monument. There are very few access roads down to the river on this map section. If you'd like a closer look, check with one of the many guides listed on the map that offer tours. Services are few and far between through eastern Montana; you will want to plan your days accordingly. The terrain continues to be rolling to hilly; by the section's end in Great Falls you'll be able to see the Front Range of the Rockies on the western horizon. ABOUT ADVENTURE CYCLING MAPS Adventure Cycling maps are created by cyclists, for cyclists, and they are some of the best available for those in search of discovery and adventure in North America. The maps reflect the association's research as well as suggestions from thousands of cyclists who have explored the Adventure Cycling Route Network. Adventure Cycling develops the best cross-country, loop, coastal, and inland cycling routes available, with turn-by-turn directions, detailed navigational instructions for the tricky sections, and elevation profiles in the high country. The maps are waterproof and designed to fit in a handlebar-bag window or jersey pocket. The maps provide information specifically for cyclists: the location of bike shops, sources for food and water, and listings of overnight accommodations including camping facilities, small hotels, and cyclists-only lodging.
