McDonald Peak, elevation 9820feet, is located in the U.S. state of Montana and is the highest peak in the Mission Mountains.[1] [3] McDonald Peak is situated within the Flathead Indian Reservation. The peak has the second greatest topographic prominence (after Crazy Peak) of all summits within Montana and is almost 80miles away from the next highest mountain in the state.[1] [4] McDonald Glacier is on the north slope of the peak.
During the summer the summit and surrounding area are inhabited by grizzly bears for the purpose of feeding on insects. Consequently, in the interests of conservation and safety, the area is closed to hikers between July 15 and September 30.[5]
