KICKING HORSE PASS First recorded in the report of the Palliser expedition of 1857-60, this pass takes its name from an incident in which Dr. James Hector, surgeon to the expedition, was kicked by his horse while exploring in this vicinity. The pass was virtually unused until after 1881 when the Canadian Pacific Railway decided to adopt it as their new route through the Rockies, foregoing the earlier preference for the more northerly Yellowhead Pass. This decision altered the location of the line across western Canada and dramatically affected the development of the West.
