About this map

The Flathead River winds through the southwestern corner of this international borderlands survey, defining a remote corridor where the United States and Canada meet. This map illustrates the transition from the protected wilderness of Glacier National Park and the Flathead National Forest into British Columbia. The terrain is characterized by a dense network of watercourses, including the central drainage of Sage Creek, which is fed by tributaries such as Nettie Cr and Elder Cr. Near the western edge, the small basin of Procter Lake sits tucked into the landscape. This 2017 edition provides a modern look at the hydrography of the Upper Flathead region, showing the exact points where these vital headwaters cross the 49th parallel.
