Mount Thompson-Seton is a mountain summit in Montana that rises to 7,815 feet. It is only modestly documented, with its recorded identity centered chiefly on its name and elevation. The peak was named for Ernest Thompson Seton, the Canadian-American author and scouting pioneer who lived from 1860 to 1946 and visited the area. That naming gives the mountain a limited but notable cultural association, connecting a Montana landscape to a figure known for writing about wildlife and helping shape early scouting traditions.
