Climbing the West Side
McDonald Peak is the highpoint of the Mission Mountains on the Flathead Reservation in Montana, and its west side approach is closed for grizzly bear protection from July 15 to October 1; confirm access and tribal permits before going. Outside the closure, the route is a demanding Class 3 scramble with steep exposure, loose rock, and snow near the summit. Storms, wind, and low visibility build quickly in this remote range. Wear a helmet, carry navigation, and start early. Respect all closures here, as this is sacred and sensitive wildlife country requiring extra care and preparation.
