1990 Map of Dennis Hill

About this map

Raft River Mountains and the northern reaches of the Sawtooth National Forest dominate this high-altitude landscape in Box Elder County. The terrain is a network of complex drainage patterns including the Right Hand Fork, Middle Fork, and Left Hand Fork that feed into the larger water systems of the basin. This map records the industrial and transport footprint of the late 20th century, highlighting the Century Mine near Century Hollow and several prospect locations. Evidence of small-scale infrastructure appears in the form of a Landing Strip and an aqueduct, alongside water management features like the Warm Spring Reservoir. From the summit of Dennis Hill to the depths of Danish Hollow, the map provides an exacting record of the springs, such as Spencer Spring and Black Hills Spring, that sustained cattle and mining operations in this arid environment.
