It is part of the Lewis Range, which spans much of the park.<ref name=topo>{{Cite map|publisher=TopoQwest (United States Geological Survey Maps)|title=Mount Stimson, MT|url=https://www.topoquest.com/map.php?lat=48.51441&lon=-113.61039&datum=nad83&zoom=4|access-date=May 24, 2018}}</ref> It is located in the remote southwestern portion of the park, approximately {{convert|5|mi|km}} west of the Continental Divide and {{convert|12|mi|km}} southeast of Lake McDonald. It is drained by Pinchot Creek (on the south) and Nyack Creek (on the other sides), both of which flow into the Middle Fork of the Flathead River. The mountain is named for Henry L. Stimson (1867–1950), former U.S. Secretary of State and twice Secretary of War, who hiked and assisted George Bird Grinnell survey the area in and around Glacier National Park in the 1890s, and supported efforts to establish the national park.
==Notability== Mount Stimson is notable for its large, steep rise above local terrain. For example, its northwest face rises over {{convert|6200|ft|m}} from Nyack Creek in only {{convert|1.8|mi|km}}. This makes it "truly a monster of a mountain."<ref name="Edwards">{{cite book | first=J. Gordon | last=Edwards | title=A Climbers Guide to Glacier National Park | publisher=Falcon | year=1995 | isbn=0-87842-177-7 }}</ref> It is also notable for its isolation; it is one of the farthest peaks from a roadhead in the park. thumb|center|350px|Aerial view of Mount Stimson's north aspect

==History== The first recorded ascent of Mount Stimson was in 1951, by J. Gordon Edwards and Alice Edwards; however they found clear evidence of a previous ascent. The standard route of ascent is the West or Northwest Face Route, starting from Nyack Creek. A backpacking trail runs along Nyack Creek, providing access; however the National Park Service warns that this is a more brushy and isolated trail than in other areas of the park, with numerous unbridged stream crossings.<ref name="SummitPost">{{cite web | url = http://www.summitpost.org/mountain/rock/349415/mount-stimson.html| title = Mount Stimson| publisher = SummitPost| access-date = 2010-05-02}}</ref> As in the rest of the park, grizzly bears are an issue as well.<ref name="NPS">{{cite web| title = Glacier NP Backcountry Guide Summer 2010| url = http://www.nps.gov/glac/planyourvisit/upload/bcguide-2010-web.pdf | archive-url = https://web.archive.org/web/20100228124124/http://www.nps.gov/glac/planyourvisit/upload/bcguide-2010-web.pdf | url-status = dead | archive-date = February 28, 2010 | year = 2010| publisher = National Park Service| access-date = 2010-11-20}}</ref> The climbing route begins with "tiresome uphill bushwhacking...for possibly three hours" leading to alternating slopes and cliffs (Grades 3 and 4).<ref name="Edwards"/> Other routes on the peak include the Southeast Spur from Martha's Basin and the Pinchot Creek Route from the south. thumb|center|400px|Mount Stimson, southwest aspect, from Stanton Lake
