About this map

Tarkio sits at a strategic bend of the Clark Fork river, where the valley floor meets the high ridges of the Lolo National Forest. The landscape is defined by its verticality, rising from the riverbank to significant summits like Cobden Peak and Graham Mtn. This area serves as a transit corridor, with Old Hwy 10 W and newer routes following the river's path, reflecting the historic movement of people and goods through these mountain passes.

Local history is anchored by sites such as the Tarkio Cem and Fish Creek Cem, providing touchstones for genealogical research in this part of Mineral County. The presence of Quartz Pasture and several named gulches, including Micayune Gulch and Mullan Gulch, points to a history of land use tied to the terrain. From the high drainage of Ninemile Divide to the confluence of Fish Creek and the main river, the map illustrates the complex drainage network that has shaped the region's development and transport routes.
