1967 Map of Corvallis

About this map

Agricultural development and water management define this portion of the Bitterroot Valley during the mid-1960s. The settlement of Corvallis serves as a local hub, supported by the Burlington Northern railroad line which includes the Corvallis Siding. The landscape is intricately carved by an extensive network of man-made waterways, including the Bitterroot Irrigation District Canal, Upper Supply Canal, and numerous lateral ditches like the Hedge Ditch and Republican Ditch. This reliance on irrigation allows for the intensive farming seen at the Western Montana Experiment Station. To the east, the terrain rises sharply toward Chaffin Butte, where the drainage of Coalpit Creek and Willow Creek transitions from mountain runoff into the valley's complex canal system. Significant local landmarks such as the Corvallis Cem and Hamilton Airport provide anchor points for genealogical and historical research.
