About this map

The Western Montana Experiment Station and the settlement of Corvallis anchor this late-twentieth-century landscape in the Bitterroot Valley. Agricultural irrigation is the defining human imprint here, visible through a complex network of man-made waterways including the Supply Canal, Hedge Ditch, and the Republican Ditch. These systems divert water to the valley floor from the rising eastern slopes where Bitterroot Nat For begins.

Evidence of early regional infrastructure remains at Corvallis Siding and along the East Side Highway, while the local topography is dominated by Chaffin Butte. Cultural landmarks such as the Corvallis Cem and High Sch provide specific points of interest for genealogists tracing family histories in the vicinity of Cobb and Quast. The eastern edge of the map transitions into the State Wildlife Management Area, marking the boundary between the cultivated valley and the rugged gulches like Coyote Gulch.
