Butte, MT

Butte perches at 5,538 feet in Montana's mountains, where I-90 and I-15 intersect to form the state's major highway crossroads. The historic mining town connects Missoula (120 miles west), Bozeman (85 miles east), and Helena (65 miles north) via these interstates. The Berkeley Pit, a massive former copper mine now filled with toxic turquoise water, serves as the city's most striking landmark.
