About this map

The Snake River carves a dramatic northern boundary for this urban and agricultural landscape, marked by the iconic drops at Shoshone Falls and Pillar Falls. The city of Twin Falls dominates the central map area, showing a well-established mid-century grid with numerous institutional landmarks such as the College of Southern Idaho and Robert Stuart Jr High Sch. The town's industrial and agricultural base is evident through the presence of a Sugar Factory and its associated Industrial Waste Ponds, as well as the Union Pacific railroad line that cuts through the heart of the community.

Suburban and rural expansion reaches south toward McMillan, while the irrigation network of the Canal system supports the surrounding fields. Local history is preserved in sites like the City Cem and the Grange Hall located near Rock Creek. This survey captures the region just before significant late-20th-century growth, documenting a landscape defined by the canyon's edge and the engineering required to move water and rail through the Idaho desert.
