1903 Map of Bonner

About this map

The Northern Pacific railroad corridor dictates the pulse of the landscape as it follows the Clark Fork through a gap between the Garnet Range and the Sapphire Range. Established early in the 20th century, this survey documents the vital junctions of the Missoula valley, including the industrial activity at Bonner where the Blackfoot River joins the main stem. Beyond the expanding streets of Missoula and the landmark University Mtn., the map reveals a network of small agricultural and timber settlements like Potomac, Clinton, and Bonita. The transition from the river valley to the steep timberlands of the Lolo National Forest is clearly defined, showing the early infrastructure of roads and mountain peaks that supported the region's mining and logging interests during its formative years.
