Nevada
Nevada is a U.S. state in the American Southwest — and in exopolitics and UAP disclosure research the single most notable geographic concentration of classified aerospace and alleged NHI program infrastructure in the United States, hosting Area 51 (Groom Lake) and the Nevada Test and Training Range within Nellis Air Force Base's administrative territory, S-4 (the alleged NHI craft facility identified by Bob Lazar) at Papoose Lake, Yucca Mountain (proposed nuclear waste storage with rumored adjacent classified facilities), and Mercury, Nevada (DOE Nevada Test Site), all within the Great Basin's remote terrain that has provided cover for classified programs since the 1950s.
Classification geography
Nevada's remoteness, sparse population, and large federal land holdings (the federal government owns approximately 85% of Nevada's land area) created the conditions for extensive classified test ranges beginning with nuclear weapons testing at the Nevada Test Site in 1951. The Nellis Test and Training Range — at approximately 12,000 square miles the largest peacetime air force range in the world — encompasses both Groom Lake (Area 51) and the Tonopah Test Range, and in UAP research is the location of a cluster of encounters including the 1994 Nellis UFO video, which shows an unidentified craft executing maneuvers impossible for any known aircraft while being tracked by military radar.
Witness concentration
Nevada — specifically the Las Vegas area — has produced a disproportionate concentration of UAP witness accounts and researcher communities, partly attributable to the proximity of Nellis, Area 51, and related facilities. The Bob Lazar disclosures (1989) originated from his residence in Las Vegas while working at S-4; George Knapp's investigative journalism broke the Lazar story through KLAS-TV Las Vegas; and Jeremy Corbell's documentary work on Lazar and the Skinwalker Ranch maintains Nevada as a hub of contemporary UAP media production.
Underground tunneling infrastructure
James Goodall, an aviation journalist with extensive access to black-program facilities, described the Nevada Test Site's tunneling capability: crews operating nuclear-powered boring machines capable of drilling a 36-foot-diameter tunnel through solid granite at approximately one foot per hour, maintaining alignment within thousandths of an inch of centerline. Per Goodall this infrastructure supports underground classified facilities with their own power (small nuclear reactors), ventilation, and access requirements. Steven Greer has independently identified the Nevada Test and Training Range as the location of a Delta Force base specifically tasked with retrieving NHI craft — both back-engineered human craft and genuine extraterrestrial vehicles — that land or crash on the range.
Project Serpo exchange site
The Nevada Test Site (northern section) was designated as the departure and arrival point for the Project Serpo personnel exchange program. According to that account, the exchange took place at the northern Nevada Test Site on July 15, 1965, after team members underwent extreme psychological and physical preparation including extended sensory-deprivation confinement.
Nevada Test Site and recovered NHI materials
Bill Uhouse — a former flight simulator engineer who claimed four years as a fighter pilot before 30 years of civilian work at Area 51 on anti-gravity propulsion systems — described being taken to the Nevada Test Site following his Area 51 work, where he saw four recovered extraterrestrial bodies. Uhouse described the Nevada Test Site as organized into distinct sections, including a nuclear testing area (the southern portion), a Nellis Air Force Base Red Flag test range, and the classified facilities surrounding Groom Lake.
Niara Isley, who served at the Tonopah Electronic Warfare Range in 1980, described recovering memories of three months of missing time associated with her Nevada posting that she attributes to a covert program operating from the classified portion of the Tonopah facility, distinct from her acknowledged radar operator duties.
Tall Whites at Nellis
Charles Hall, a nuclear physicist who served as a U.S. Air Force weather specialist at Nellis Air Force Base from 1965 to 1967, described sustained encounters with a non-human species designated Tall Whites during isolated tours at the Indian Springs Gunnery Ranges north of Las Vegas. Hall — who held top secret orders and operated under a cover story involving routine meteorological observation — described encounters with tall, pale, luminescent beings that other base personnel had explained away as "the legend of Range Four Harry," a supposedly ghostly radioactive horse roaming the desert. Hall documented these encounters in his Millennial Hospitality book series and has been corroborated by other witnesses who reported similar figures in the same Nevada range areas during the same period.
2023 Las Vegas backyard sighting
In April 2023, a Las Vegas family filed a police report describing large non-human beings that landed in their backyard following a bright flash of light. The incident, which occurred in the North Las Vegas area, was corroborated by a responding officer who also observed something anomalous. Las Vegas Metropolitan Police Department body camera footage captured a flash consistent with the family's account, and the case gained national attention — adding Nevada to the contemporary record of domestic NHI encounter reports alongside its historical role as a classified aerospace hub.
