One of the backcountry routes I enjoy the most is the 19th-century road over Bannack Pass, in the Beaverhead Mountains along the Continental Divide between eastern Idaho and southwestern Montana.
More than a century ago, the old Bannack road linked Montana's territorial capital, today's ghost town at Bannack State Park, with Corinne, Utah, not far from the Transcontinental Railroad.
Today, it is a little-traveled single-lane dirt road that combines homestead-era log structures, inspiring northern Rocky Mountain scenery, a gear-soaking stream ford and easy access to a day-long loop.
