About this map

The Idaho National Engineering Laboratory dominates the central landscape of this 1970s survey, marking a significant era of nuclear research in the high desert. Along its southern reaches, the Experimental Breeder Reactor No 1 stands as a landmark of atomic history, located near the junction of Van Buren Blvd. The presence of numerous Borrow Pits and a Drill Hole across the plain suggests the intensive construction and geological testing associated with the facility's development.

Water management and transportation are defined by the Big Lost River, which is monitored by multiple Gaging Station locations as it flows near the Union Pacific rail line. To the northwest, the open expanse of Deadman Flat is crisscrossed by a Jeep Trail, illustrating the contrast between the high-tech laboratory infrastructure and the primitive access routes that still serve the surrounding Idaho terrain.
