Few places on earth carry a Cold War imprint quite as visibly as the Nevada desert. Craters the size of city blocks sit baked into the earth northwest of Las Vegas, not far from one of the most visited tourist corridors in the world. Most people flying into McCarran have no idea they’re passing over ground that absorbed more than nine hundred nuclear detonations. This is not ancient history. The physical scars remain. The legal arguments are still being written. And the communities that lived downwind of those blasts are still, in 2026, waiting for something closer to justice.
A Site Chosen for Its Emptiness
The Nevada Test Site was established in December 1950 when President Harry S. Truman authorized the designation of a portion of the Nellis Air Force Gunnery and Bombing Range for testing American nuclear devices by the U.S. Atomic Energy Commission. The choice of location was deliberate. The site encompassed over 1,360 square miles of federal land, much of it uninhabited desert – an immense expanse that theoretically provided a buffer zone large enough to contain the physical effects of atomic blasts.
In the aftermath of World War II and the harrowing bombings of Hiroshima and Nagasaki, the United States found itself in a new geopolitical landscape: the Cold War. The Soviet Union’s detonation of its first atomic bomb in August 1949 ignited a fierce arms race, prompting an urgent need for the U.S. to rapidly advance its nuclear capabilities. Nevada was, in a sense, selected precisely because it appeared forgettable on the map.
The Scale of Testing: Numbers That Still Stagger
The Nevada Test Site was the location for 928 of 1,054 U.S. nuclear tests, including 100 atmospheric nuclear test explosions between 1951 and 1962 and another 828 tests performed underground. That is not a typo. Nearly a thousand nuclear weapons were detonated in a single patch of American desert over four decades.
The mushroom clouds from the 100 atmospheric tests were visible from almost 100 miles away and could be seen from the Las Vegas Strip in the early 1950s. The city of Las Vegas experienced noticeable seismic effects, and the distant mushroom clouds, which could be seen from the downtown hotels, became tourist attractions. The spectacle drew crowds. The risks went largely unmentioned.
What the Blasts Left Behind in the Ground
The Nevada National Security Site was used from 1951 to 1992 to conduct a total of 100 atmospheric and 828 underground nuclear weapons tests. As a result, some groundwater, surface soils, and industrial-type facilities were contaminated on the site and the surrounding Nevada Test and Training Range…
