Salmon to Chadron: A Cross-Country Road Trip Guide

Your journey begins at the confluence of the Salmon and Lemhi Rivers, where the Salmon River earned its nickname 'The River of No Return' due to its rugged, unnavigable canyons. From there, you'll traverse the Continental Divide at Monida Pass (elevation 6,870 feet), crossing from the Pacific to the Atlantic watershed before descending into the Great Plains.

This 780-mile route, if driven direct, takes about 13 hours without stops. Yet the real value lies in the vast, empty landscapes and unexpected historical layers. The route crosses three states, two time zones (Mountain to Central at the Montana-North Dakota border), and a geological transition from the Northern Rockies to the High Plains.

According to the American Petroleum Institute, as of October 2023, gas prices along the route average $3.75 in Idaho, $3.50 in Montana, and $3.30 in Nebraska, making a fuel budget of roughly $110 for an average sedan.
