1963 Map of Dillon West

About this map

Dillon serves as the focal point of this valley landscape, where the Union Pacific railroad line mirrors the winding course of the Beaverhead River. The 1963 survey, updated with 1970s aerial data, reveals a highly managed hydrological system critical to the region's agricultural life. Numerous irrigation works like the East Bench Canal, Side Canal, and Haines DITCH crisscross the valley floor, working alongside natural features like Poindexter Slough and Smith Island. In the north, the urban character of the town is marked by its High Sch, the Fairground, and a Drive-in Theater, while to the south, the Beaverhead Canyon Gateway signals a transition into more constrained terrain near the settlement of Barretts. Local history is preserved in landmarks such as the Blacktail Sch and various family-named features like Tulley Spring.
