1958 Map of Boise

About this map

The Union Pacific railroad corridor anchors the agricultural and urban heart of the Treasure Valley in the late 1950s, connecting Idaho's growing capital at Boise with the industrial hubs of Nampa and Caldwell. The landscape transitions from the irrigated fields near the Boise River and Lake Lowell to the high desert and mountain terrain of the Mahogany Mountains and War Eagle Mountain. To the south and west, the vast river system defined by the Snake River and Owyhee River reveals a network of remote outposts like Jordan Valley and the site of Rockville (Abandoned). Mapping of the region is oriented by Initial Point, the fundamental survey marker for the state. Significant water management and conservation efforts are evident through the Deer Flat National Wildlife Refuge and large-scale infrastructure such as Swan Falls and the C. J. Strike Reservoir.
