About this map

Twin Bridges sits at the vital confluence where the Beaverhead River and the Big Hole River join to form the Jefferson River. This 1960s landscape is defined by its complex irrigation network, featuring the Tash Slough, Parrot Ditch, and Seyler-Tash Ditch, which support the ranches and valleys below the Highland Mountains. The map documents the civic and industrial footprint of the era, from the State Childrens Center and Municipal Airport near the town center to the Northern Pacific railroad tracks that parallel the water.

In the higher elevations of the Deer Lodge National Forest and the Ironrod Hills, the legacy of Montana mining is evident. Numerous claims and operations like the Keystone Mine, Victoria Mine, and Clancy Mine dot the slopes, while family-named landmarks like Pogliano Ranch and the Pageville School provide specific points of interest for genealogists tracing local residents of Madison and Silver Bow counties.
