Nuclear testing sites: craters and cities you can visit

An overground granite monument marks the site of the only US atomic bomb tests east of the Rocky Mountains. Part of Project Dribble, these two bombs were aimed at finding out whether a country could muffle the shock wave from a nuclear explosion by setting it off in an underground cavern. The site is accessed by appointment only.

Sedan Crater - Nye County, Nevada -

In 1962, a shaft descending over 600 feet (182 m) into the desert floor was created, and the Sedan bomb was lowered into it. When the 104-kiloton bomb was detonated, it lifted the ground above it into a dome over 300 feet (91 m) high, sending a massive shockwave of dirt.

Today, the giant crater is still there in the middle of the desert, and monthly tours of the site are given.

Runit Island - Marshall Islands -

Between 1946 and 1962, the US military conducted 105 atmospheric nuclear tests over the Marshall Islands and several other nearby South Pacific atolls.

In the late '70s, in an effort to clean up the radioactive debris left by those explosions, the government dug up 111,000 cubic yards of soil from the Bikini and Rongelap atolls and deposited it on Runit Island.

Covering up that giant radioactive pit cost the government nearly a quarter of a billion dollars and took three years to complete. The result is an enormous dome, called the Cactus Dome, consisting of 358 gigantic concrete panels.

Project Shoal Site - Fallon, Nevada -

Project Shoal was an underground nuclear test that took place on October 26, 1963, approximately 30 miles (48 km) southeast of Fallon, Nevada.

The site was selected because its earthquake activity afforded a basis for seismic signal comparisons. Today, you can visit the monument, which, in contrast to many historic nuclear test sites, you can drive right up to.

Rulison Nuclear Test Site - Parachute, Colorado -

On September 10, 1969,the United States Atomic Energy Commission detonated a 40-kiloton nuclear bomb (nearly twice as powerful as the one dropped on Hiroshima at the end of World War II) 8,400 feet (2.5 km) beneath the rural community of Rulison, Colorado.

Mars Bluff Crater - Florence, South Carolina -

On March 11, 1958, a US Air Force B-47 Stratojet with a nuclear bomb accidentally released it. The resulting explosion created a crater estimated to be 75 feet (23 m) wide and 25–35 feet (7.6–10.7 m) deep. It destroyed a local playhouse and leveled nearby trees. No one was killed.

Atomic Survival Town - Nye County, Nevada -

In 1955, 14 nuclear test explosions known as Operation Teapot were set off in the Nevada desert at Yucca Flat.

The project included purpose-built homes and other structures, set at varying distances from the blasts, to test the impact of the explosions. Today, public tours are available.

Secret City - Oak Ridge, Tennessee -

The city of Oak Ridge was established by the US government in 1942 to serve as a home base for the Manhattan Project.

Secret City - Oak Ridge, Tennessee -

Chosen for its remote location, the entire city had to be built almost from scratch to handle the influx of employees and residents, which went from 3,000 to 75,000 within three years. The Secret City Festival, complete with WWII reenactors, happens every June.

Nuclear testing sites: craters and cities you can visit

How about exploring these nuclear testing sites on your upcoming vacation?

TRAVEL Dark tourism

On July 16, 1945, the first nuclear explosion occurred a few hundred miles south of Los Alamos, New Mexico. Known as the Trinity test by J. Robert Oppenheimer, the director of the Los Alamos Laboratory, it was the start of the age of nuclear weapons. From that day until 1992, the US alone conducted more than 1,000 nuclear tests. And, perhaps surprisingly, many of the sites where these earth-shattering explosions took place can still be visited today.
