This mountain on the border between Alberta and British Columbia is also on the 120th meridian of west longitude. South of Intersection Mountain, the interprovincial border is along the continental divide. North of Intersection Mountain, the border is on the 120th meridian.

British Columbia’s boundary was specified by the British Parliament in 1866, in the act that united the colonies of Vancouver Island and British Columbia. Article 7 states that B.C.’s boundary on the east is “the Rocky Mountains and the 120th meridian of west longitude.”
