Gwillim Lake, BC was named after Professor John Cole Gwillim who was appointed professor of mining at Queen's University at Kingston in 1903. His work included exploring the coal lands in this area and oil fields of Alberta for the CPR and later in 1919, field work for the British Columbia government. He created a map of the Tumbler Ridge area which included the "Rocky Mountain Lake" and died shortly after in 1920. That lake was renamed Gwillim Lake in 1921 in his memory.
