While exploring these mountains in the summer of 1865, Walter Moberly, assistant surveyor-general of British Columbia, noted the flight of eagles through a break in the Gold Range (Monashees), thereby discovering Eagle Pass. After 1881, Eagle Pass was chosen as the Canadian Pacific Railway’s route between the drainage basins of the Columbia and Fraser rivers. This was one of the last stretches of the railway to be completed, and on 7 November 1885, Sir Donald Smith drove the “last spike” here, in the pass, at Craigellachie. *Note: This designation has been identified for review.
