Chief Mountain Border Crossing, Waterton Lakes National Park

The Chief Mountain Border Crossing connects the town of Babb, Montana with Pincher Creek, Alberta on the Canada–US border. Montana Highway 17 on the American side joins Alberta Highway 6 on the Canadian side, creating the only road border crossing within the Waterton-Glacier International Peace Park. Poker Creek–Little Gold Creek and this crossing are the only ones closed in winter. ()
