Anthill
The "Anthill" is the colloquial name applied by UFO researchers to the alleged network of deep underground tunnels and facilities beneath the Northrop Tehachapi Ranch radar cross-section (RCS) test facility in Kern County, California. The name derives from the large volume of testimony suggesting the underground complex is so extensive — reportedly with up to 42 levels — that the site resembles an anthill in scale and interconnection. The Anthill is considered the central underground hub of the broader Antelope Valley UAP legacy program complex.
Physical Description from Witness Testimony
Based on firsthand accounts compiled primarily by researcher Bill Hamilton, the Anthill is described as follows:
- A local resident reported that the ground near Tehachapi would open "like a missile silo" from which a flying saucer took off; the witness was silenced by Edwards AFB OSI personnel.
- Contractor "Chuck" described digging the underground tunnels beneath the Anthill himself, reporting round doorways with few doors and red and green lights for identification and entry.
- A source claiming work on "Project Star Talk" described a large underground building using lasers "for the purpose of constructing systems to bring in UFOs," mentioning scalar technology consistent with what Steven Greer later discussed publicly as a UAP downing mechanism.
- The same Star Talk informant claimed to have also worked at the McDonald Douglas STIF, where he observed a UAP held in an underground hangar.
- An informant called "Gober" claimed to work at Tehachapi, Helendale, and the Nevada Test and Training Range with alien technology that "deeply frightened him." Gober reported that on-site personnel rotate every 14–16 days, living and working on-site, and that a command center exists under Haystack Butte — connecting to other facilities.
- Multiple informants described ground electric vehicles and maglev train systems within the underground complex.
Command Structure and Geography
Bill Hamilton and independent researchers including Steven Greer and forensic artist Bill McDonald have variously described the Anthill command center as located beneath Haystack Butte at Edwards Air Force Base (approximately 40 miles east of Tehachapi). This suggests the Anthill is not an isolated facility but a node in a larger command-and-control structure anchored at Edwards.
The estimated 42 underground levels cited by some sources would make the Anthill among the deepest alleged underground facilities in the US, exceeding even the proposed depths of the Deep Underground Command Center (DUCC) below the Pentagon (proposed at 3,500 feet). Steven Greer has claimed personal knowledge of the Anthill's entrance and to have been flown over RCS facilities in the Antelope Valley where he observed what appeared to be trough-like structures from which craft emerge vertically.
Radar Cross-Section Facility Cover
The surface Tehachapi Ranch facility is an acknowledged Northrop Grumman radar cross-section (RCS) test range. RCS facilities feature large runways, pylons raised from underground on concrete diamonds, and underground storage for test equipment — characteristics that provide natural cover for underground construction. Much of the Cold War RCS facility was specifically built underground to conceal pylon equipment and models from Soviet spy satellites. This pre-existing underground infrastructure at RCS sites is cited as potentially providing ready access to deeper underground expansion.
