Sentry Mountain

Sentry Mountain is a 2,435-metre summit in the Canadian Rockies of southwestern Alberta, near Crowsnest Pass west-southwest of Coleman. At the northern end of the Flathead Range, it rises sharply above Crowsnest Lake, with 1,080 meters of relief over just 1.5 kilometers, making it a striking landmark visible from Highway 3. Its runoff feeds the headwaters of the Crowsnest River. Originally called Sentinel Mountain, it was renamed in 1915 to avoid confusion with another peak, and the present name was officially adopted in 1924. The mountain is composed of ancient sedimentary rock later thrust over younger Cretaceous strata during the Laramide orogeny.
