About this map

Upper Holter Lake and the winding Missouri River define this portion of Lewis and Clark County, where the waterway carves through steep canyons and gulches. The landscape reflects a legacy of ranching and early settlement, anchored by the Hilger Ranch and the historic Old Weiss and French Place. These sites, situated near Hilger Valley and Spring Gulch, point to the importance of water access and sheltered valleys for homesteading in the Montana interior.

Transportation and infrastructure are concentrated along the river corridor, dominated by the Hauser Dam to the south. The dam creates Hauser Lake, a significant reservoir that supports local recreation at spots like the Hauser Dam Sportsmans Access and Black Sandy Beach. Rugged side drainages such as Coulter Canyon and Meriwether Canyon offer insight into the topographical challenges that shaped the routes of Gates of the Mountains Rd and American Bar Rd.
