1992 Map of Eureka

About this map

Eureka serves as the industrial and social anchor of this 1992 landscape, situated at the base of Eureka Ridge in the northern Tintic Mountains. The map reveals a complex web of extraction history across Godiva Mountain and the surrounding canyons, where numerous legacy workings like the Mammoth Shaft and the Iron King No 1 Tunnel are recorded. While Eureka and Mammoth remain active points on the map, the presence of several locations marked as sites—such as Knightville, Homansville, and Diamond—indicates the shifting footprint of the mining boom. Transportation history is etched into the terrain by the Union Pacific Railroad Grade, which once connected these high-altitude operations to the broader valley. From the educational hub at Tintic High School to the quiet corner of the Cemetery, the map documents a community deeply intertwined with the geology of the Goshen Valley fringe.
