1988 Map of Triangle Mountain

About this map

The Nellis Air Force Range (Restricted Area) dominates this high-desert landscape in Nye County, Nevada, reflecting the region's mid-century transition to a dedicated military testing and training zone. The terrain is defined by a series of distinct geological formations, including the prominent Triangle Mountain and the sweeping Coyote Cuesta. In the northern section, the Lizard Hills rise above Cactus Flat, while the southern expanse transitions into the broad reach of Gold Flat. This 1988 provisional map documents the restricted land use of the era, noting a specific Gold Mountain peak and several unnamed landing sites or observation points within the military boundaries. The lack of civilian infrastructure, such as towns or commercial roads, underscores the isolated, tactical nature of this specific quadrant of the Nevada desert during the late Cold War period.
