From 1907 through 1909, the Milwaukee Road blasted a route through the Bitterroots, into the Inland Northwest and onward to Puget Sound. Today, you can explore the most spectacular section of the route on a bike or on foot. It's called the Route of the Hiawatha, and mountain bikers flock to this trail from all over the country. Now, a new book titled "The Milwaukee Road's Western Extension," by Stan Johnson (Museum of North Idaho), tells a story as spectacular as the scenery.
