1919 Map of Big Sandy

About this map

Big Sandy serves as the central hub on this 1919 tactical map, situated at the junction of Big Sandy Creek and the Great Northern Railway Line. The landscape is defined by the transition from the high plains of Hill Co. down to the deep incision of the Missouri River near the settlement of Virgelle. A sophisticated network of drainages and coulees, such as Fourteen Mile Coulee and Rainbow Coulee, illustrates the complex erosion patterns of the northern Montana prairie. Along the southern edge of the sheet, a Ferry crossing indicates a critical transport link over the Missouri before the widespread construction of bridges. The map reveals early 20th-century water management efforts through the Havre Reservoir and various unnamed reservoirs, reflecting the importance of irrigation and steam-locomotive supply in this semi-arid region. Small rail stops like Verona, Cairo, and Laredo provide a detailed look at the rail-dependent economy that sustained these rural townships after the turn of the century.
