					  Geological Survey of CanadaThe Geological Survey of Canada publishes George Dawson’s geological map of the Canadian Rockies. The map covers the Canadian Rockies from the border with the United States to the Red Deer Valley in central Alberta and includes Turner Valley and Bow Valley and was an important resource for natural resource exploration.

					  Herron Acquires Land and Drilling RightsWilliam Stewart Herron, shown here ca. 1930, noticed gas seepages along the Sheep River and acquired land and drilling rights for the area. He partnered with Archibald W. Dingman and a group of Calgary-area investors to form Calgary Petroleum Products and began drilling in Turner Valley in 1913.

					  Royalite Takes OverA fire and explosion in October 1920 severely damage the Calgary Petroleum Products plant at Turner Valley. Unable to continue operations, the company is taken over by Imperial Oil in 1921. Imperial Oil forms a subsidiary company called Royalite to manage the plant and wells in the valley. New absorption and compression plants are built as well as a pipeline to Okotoks, which, on December 31, feeds gas into the Canadian Western Natural Gas line to Calgary.

					  ConservationAfter years of concerns about flaring waste gas, the Government of Alberta enacts the Oil and Gas Resources Conservation Act. This Act results in the creation of the Petroleum and Natural Gas Conservation Board, which is endowed with the authority to regulate all gas and oil operations and to enforce better conservation measures.
