Set on the southern rim of the Columbia Icefields, with no other peak encroaching on its domain for many miles, there are no masking barriers close at hand to cut off the view in any direction. Not only are almost all the great peaks of the Canadian Rockies system notched into the splendid panorama, but also many of those of the Selkirk and Gold Ranges, far beyond the purple-shadowed depths that mark the great gorge of the Columbia River.[3]}}GeologyCastleguard is composed of sedimentary rock laid down during the Precambrian to Jurassic periods.[4] Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny.[5] ClimateBased on the Köppen climate classification, Castleguard is located in a subarctic climate with cold, snowy winters, and mild summers.[6] Temperatures can drop below −20 °C with wind chill factors below −30 °C.
