1955 Map of Firth

About this map

The Snake River corridor in Bingham County serves as the lifeblood of this mid-century landscape, fueling a complex irrigation network of canals and ditches. The communities of Firth, Basalt, and Shelley are linked by the Union Pacific railroad and Highway 91-191, which run parallel to the river's eastern bank. A distinctive geological transition is visible on the western side of the river, where the lava fields of the Snake River Plain dominate the terrain, contrasting sharply with the fertile, canal-fed agricultural land to the east.
