Hamilton serves as the central hub of this early 20th-century landscape, where the Northern Pacific Railway Bitterroot Branch dictates the settlement pattern along the valley floor. The map captures a period of active resource extraction and early community infrastructure, evidenced by industrial sites like the Curlew Mines and the Bluebird Mine near Victor. Education and leisure also have their place in this developing frontier, marked by the Pleasantview School and the Weeping Child Hot Springs. To the west, the formidable Bitterroot Mountains rise sharply, their drainage represented by a complex network of creeks including Lost Horse Creek and Blodgett Creek. This survey provides a clear look at the valley's transition from the wild terrain of the Bitterroot National Forest to the organized agricultural and mining districts around Grantsdale and Corvallis.
