Cold War nuclear weapons storage facility video now available
Los Alamos National Laboratory sits on top of a once-remote mesa in northern New Mexico with the Jemez mountains as a backdrop to research and innovation covering multi-disciplines from bioscience, sustainable energy sources, to plasma physics and new materials.

Down a remote canyon near Los Alamos National Laboratory lies a facility known as the "Tunnel Vault," once one of the most secret and secure locations in the United States, it's the original post-WWII nuclear stockpile storage area.

Located in Los Alamos canyon at Technical Area 41, the Tunnel Vault was built between 1948 and 1949.  The facility has a formidable security perimeter, a hardened guard tower—complete with gun ports and bulletproof glass—and a series of gates and doors that lead to a 230-foot long concrete tunnel that goes straight into the canyon wall.

At the end of the tunnel is a large alcove room with a single bank vault door. Through that door is a vault built inside a vault with five storage areas, all protected with identical bank vault doors. All these features can be seen on a video that tours the recently declassified, historically significant facility.

As part of the Laboratory's 70th anniversary "Signature Week" the Tunnel Vault will be one of the stops on two tours during the week of July 22, one tour will be open to working news media, and the other tour will be part of the Laboratory's family celebration for employees and their family members.

Over the years the Tunnel Vault was also used as a nuclear materials and area, a weapons research and development laboratory, weapons components , and nuclear material assembly for tests both in the Pacific and in Nevada.

"This facility had a long history during the cold war. So this was definitely a top secret, very secure location," said McGehee.

About halfway down the tunnel is a side room that was used for early development of unclassified research that led to the discovery of the neutrino—work that later won a Nobel Prize in physics—a lab space ideal for the work because it's buried 300-feet deep underground.
