1986 Map of Yucca Flat

About this map

Nevada Test Site operations define the landscape of Yucca Flat during this mid-1980s period of government activity. The map reveals an intricate network of specialized infrastructure supporting nuclear research and testing, including numerous Drill Holes, a designated Blast Center, and the Area 3 Mud Plant. The terrain is marked by utility and logistical hubs such as B J Wye and several substations, reflecting the intensive development of this high-security zone. Transportation is centered on specialized routes like the Mercury Highway, Pahute Mesa Road, and Rainier Mesa Road. Beyond the industrial footprint, natural landmarks like Balloon Hill stand above a valley floor pockmarked by extensive Borrow Pits and gravel extractions, illustrating the scale of land alteration required for the site's unique mission.
