Which of the following is untrue about Tunnel Mountain in Alberta, Canada?

Tunnel Mountain is located in the Bow River Valley of Banff National Park in Alberta, Canada and is nearly completely encircled by the town of Banff. It gives its name to the Tunnel Mountain Formation, a geological formation. The Stoney people had long called the mountain "Sleeping Buffalo", as it resembles a sleeping buffalo when viewed from the north and east. In constructing a route through Rockies the Canadian Pacific Railway originally intended to tunnel through the mountain, but an alternative route north of the mountain was found, which shortened the railway by a mile, and avoided two long hills, saving the CPR millions of dollars. So "Tunnel Mountain" contains no tunnel!
