Mount Costigan

Mount Costigan is a steep 2,973-metre peak in Alberta, north of Lake Minnewanka at the boundary between Banff National Park and the Ghost River Wilderness Area. Rising nearly 1,500 metres above the lake in just 4 kilometres, it stands out sharply in the landscape. Named in 1904 for Canadian judge and politician John Costigan, who often visited the area, the name was officially adopted on November 2, 1956. The mountain is formed from sedimentary rock laid down from the Precambrian to the Jurassic and later thrust eastward over younger rock during the Laramide orogeny. Its subarctic climate brings cold, snowy winters, mild summers, and runoff into Ghost River tributaries.
