Cactus Springs is a small community in Clark County, Nevada located on US Highway 95, about 60 mi northwest of Las Vegas in the Mojave Desert.
 It is near Indian Springs and the Nevada Test Site.
 Cactus Springs is also the site of "The Temple of Goddess Spirituality Dedicated to Sekhmet", the Egyptian goddess, built in 1993, "founded on the principles of Peace, Goddess Spirituality & the gift economy" by Genevieve Vaughan.
 The annual interfaith Sacred Peace Walk, conducted and organized by the Nevada Desert Experience, is supported, in part, by the temple on the peacewalk's way to the Nevada Test Site's southern gate.
William Joseph ("Wild Bill") Donovan (January 1, 1883 – February 8, 1959) was an American soldier, lawyer, intelligence officer and diplomat.
 Donovan is best remembered as the wartime head of the Office of Strategic Services (OSS), the precursor to the Central Intelligence Agency, during World War II.
 He is also known as the "Father of American Intelligence" and the "Father of Central Intelligence".
 "The Central Intelligence Agency regards Donovan as its founding father," according to journalist Evan Thomas in a 2011 "Vanity Fair" profile.
 The lobby of CIA headquarters, in Langley, Virginia, now features a statue of Donovan.
 Thomas observed that Donovan's "exploits are utterly improbable but by now well documented in declassified wartime records that portray a brave, noble, headlong, gleeful, sometimes outrageous pursuit of action and skulduggery."
Douglas Seymour Mackiernan (April 25, 1913 – April 29, 1950) was the first officer of the Central Intelligence Agency (CIA) to be killed in the line of duty.
 He worked as a cryptographer for the United States Army Air Forces and was then posted to China as an Air Force meteorologist during World War II.
 By 1947, he had quit the Air Force and was employed as a covert intelligence officer by the CIA.
 As a cover for that work he was assigned the position of Vice-Consul for the U.S. State Department at its consulate in Ürümqi (Tihwa) in East Turkestan (modern Xinjiang).
 There his scientific talents (he dropped out of the Massachusetts Institute of Technology after his freshman year) were employed in espionage.
 Until 2002, the CIA successfully hid the fact that Mackiernan was America's first atomic spy; Mackiernan's collection of atomic intelligence about the Soviet Union's first atomic bomb (tested just across the border at the Semipalatinsk Test Site in Kazakhstan) was first revealed by the journalist Thomas Laird, but only confirmed by the CIA in 2008.
BREN Tower was a guyed steel framework mast, 1527 ft high, on the Nevada Test Site in Nevada, USA.
 "BREN" stands for "Bare Reactor Experiment, Nevada."
 The structure was owned by the Department of Energy and maintained by National Security Technologies.
 Access to the tower area had been closed since July 2006.
 No reason for the closure has been given.
 As part of the Nevada Test Site, it was also located in restricted airspace (R-4808N).
The National Intelligence Authority (NIA) was the United States Government authority responsible for monitoring the Central Intelligence Group (CIG), the successor intelligence agency of the Office of Strategic Services established by President Harry S. Truman's Executive Letter of 22 January 1946 in the aftermath of World War Two.
 The National Intelligence Authority and Central Intelligence Group were both replaced respectively by the National Security Council and the Central Intelligence Agency under the National Security Act of 1947 implemented on the 18 September 1947.
The Intelligence Star is an award given by the Central Intelligence Agency to its officers for "voluntary acts of courage performed under hazardous conditions or for outstanding achievements or services rendered with distinction under conditions of grave risk".
 The award citation is from the Director of the Central Intelligence Agency and specifically cites actions of "extraordinary heroism".
 It is the third-highest award given by the Central Intelligence Agency, behind the Distinguished Intelligence Cross and Distinguished Intelligence Medal, and is analogous to the Silver Star, the US military award for extraordinary heroism in combat.
 Only a few dozen people have received this award (most posthumously), making it one of the rarest valor awards awarded by the US government.
The United States Air Force facility commonly known as Area 51 is a highly classified remote detachment of Edwards Air Force Base, within the Nevada Test and Training Range.
 According to the Central Intelligence Agency (CIA), the correct names for the facility are Homey Airport (ICAO: KXTA) and Groom Lake, though the name "Area 51" was used in a CIA document from the Vietnam War.
 The facility has also been referred to as "Dreamland" and "Paradise Ranch", among other nicknames.
 The special use airspace around the field is referred to as Restricted Area 4808 North (R-4808N).
The Nevada National Security Site (N2S2),(though the abbreviation NNSS is still used), previously the Nevada Test Site (NTS), is a United States Department of Energy reservation located in southeastern Nye County, Nevada, about 65 miles (105 km) northwest of the city of Las Vegas.
 Formerly known as the Nevada Proving Grounds, the site was established on 11 January 1951 for the testing of nuclear devices, covering approximately 1,360 square miles (3,500 km) of desert and mountainous terrain.
 Nuclear weapons testing at the Nevada Test Site began with a 1-kiloton-of-TNT (4.2 TJ) bomb dropped on Frenchman Flat on 27 January 1951.
 Many of the iconic images of the nuclear era come from the NTS.
 NNSS is operated by National Security Technologies, LLC, a joint venture of Northrop Grumman, AECOM, CH2M Hill, and Babcock & Wilcox.
Mercury is a closed city in Nye County, Nevada, United States, 5 mi north of U.S. Route 95 at a point 65 mi northwest of Las Vegas.
 It is situated within the Nevada Test Site and was constructed by the Atomic Energy Commission to house and service the staff of the test site.
 The specific site was known as Jackass Flats, NV and nearby Nevada Test Site 400.
 Today, the site is governed by the United States Department of Energy.
 As part of the test site, the town is not accessible to the general public.
 It was named after the mercury mines which flourished in its general vicinity a century before the town itself was established.
 The current population is unknown.
