Ex Coelis Mountain

Ex Coelis Mountain is a 2,545-metre (8,350-foot) mountain with five peaks located in the North Saskatchewan River valley of the Canadian Rockies of Alberta, Canada. It is situated south of Abraham Lake and just outside the eastern boundary of Banff National Park.[4] Its nearest higher peak is Hatter Peak, 8.0 km (5.0 mi) to the southeast.[1] Ex Coelis Mountain can be seen from the David Thompson Highway east of Saskatchewan Crossing. Ex Coelis Mountain is composed of sedimentary rock laid down from the Precambrian to Jurassic periods that was pushed east and over the top of younger rock during the Laramide orogeny.[5]


In 1911 it was originally known as Kadoona Mountain by Mary Schäffer which is a corruption of the Stoney name Kedonnaha Tinda (Meadow of the Winds) and is today known as the Kootenay Plains.[1]

The mountain's name became official in 1994 when approved by the Geographical Names Board of Canada to honor the 1st Canadian Parachute Battalion.[3] In Latin, Ex Coelis means Out of the Clouds and is their motto.

In 1997 the five peaks of Ex Coelis Mountain were assigned individual names. Normandy Peak, Ardennes Peak, and Rhine Peak were named for World War II battles in which the battalion participated. Elbe Peak was named for the river near where the battalion met the Russian Army. Stan Waters Peak is named for Stanley Waters, a battalion member.[1]
