1901 Map of Hamilton

About this map

The Bitterroot River valley serves as the central artery for this late nineteenth-century landscape, where early irrigation networks and silver-lead mining defined the local economy. A complex system of water engineering is evident through labels like Republican Ditch, Hedge Ditch, and Cow Ditch, which redirected mountain runoff to support agriculture around Corvallis and Hamilton. To the west, the steep Bitterroot Mountains rise sharply, dotted with early industrial operations such as the Curlew Mines, Bluebird Mine, and Pleasantview Mine near Dutch Hill. The Bitterroot Branch N. P. R. R. follows the river, connecting established valley settlements including Victor, Woodside, and Grantsdale. This survey, conducted by E.C. Barnard and A.B. Searle, documents the region's transition from a mining frontier to an organized agricultural hub just before the turn of the century.
