Continental Divide crests through this high-altitude borderland, marking the dramatic boundary between Gallatin County, Montana, and Fremont County, Idaho. The landscape is dominated by the Henrys Lake Mountains, where peaks like Lionhead and Bald Peak overlook the headwaters of both the West Fork Gallatin River and Targhee Creek. This 2000 revision shows a region primarily defined by its transition from high mountain wilderness to the valley floor of Henrys Lake, featuring the Landing Field and Targhee Cemetery near the shoreline.
