It lies within Itcha Ilgachuz Provincial Park. Name originMount Downton was named for Geoffrey M. Downton, British Columbia Land Surveyor, for whom Downton Lake, the reservoir behind Lajoie Dam in the Bridge River Power Project is also named. Downton is credited with first noting the hydroelectric potential inherent in the elevation differential between the Bridge River and Seton Lake on opposing sides of Mission Pass during a visit to the Bridge River Mining District in 1912.[3] GeologyMount Downton is part of the Anahim Volcanic Belt, a west-east trending line of volcanoes formed when the North American Plate moved over a hotspot, similar to the one feeding the Hawaiian Islands, called the Anahim hotspot. The Anahim Volcanic Belt includes other immediately nearby ranges, the Rainbow and Ilgachuz Ranges. See also{{Portal|Volcanism of Canada}}
