About this map

The county seat of Chinook serves as a vital hub for Montana’s high plains, defined by the winding course of the Milk River and a sophisticated network of irrigation systems. In the mid-1960s, the town’s economy is visibly tied to both agriculture and industry, featuring an Oil Refinery and numerous Gravel Pits alongside the tracks of the Great Northern railroad. The landscape is etched with complex water management features like the Fort Belknap Canal, Paradise Valley Canal, and Matheson Ditch, which support the surrounding valley floor.

Beyond the central town, the topography rises into a series of coulees, including Redrock Coulee and Sixmile Coulee. Local infrastructure of the era is well-represented by the Drive-in Theater and Airfield on the western edge of town, while the East Chinook Sch and the named Barney Olson Road provide specific points of interest for genealogists and local historians tracing family holdings in the Missouri River Basin.
