NATIONAL ATOMIC TESTING MUSEUM TO COMMEMORATE 60th ANNIVERSARY OF SEDAN CRATER FORMATION WITH ROUNDTABLE DISCUSSION, SATURDAY, JULY 30
Historic Nuclear Blast Created Largest Man-Made Crater in United States
LAS VEGAS (July 2022) – To commemorate the 60-year anniversary of the formation of the Sedan Crater, the largest man-made crater in the United States created on July 6, 1962, the National Atomic Testing Museum (NATM) will host a roundtable discussion on Saturday, July 30 from 10 to 11:30 a.m. Guests are invited to learn more about one of the most significant blasts in atomic testing history and the crater that formed as a result. During the event, three former Nevada Test Site employees and current trustees for the Nevada Test Site Historical Foundation will share their remembrances about Sedan and answer moderator-led questions. Attendees will then have the exclusive opportunity to enjoy breakfast with the speakers and ask their own questions at this casual meet and greet.
Roundtable speakers include:
• Peggy Hallerberg has been associated with programs at the former Nevada Test Site for more than 40 years. She is also a founding member of the Nevada Test Site Historical Foundation and the National Atomic Testing Museum as well as a former executive with national defense contractor EG&G, Inc.
• Darwin Morgan is president of the National Atomic Testing Museum board of trustees. He is also a founding member of the Nevada Test Site Historical Foundation and the National Atomic Testing Museum as well as the former director, Office of Public Affairs, U.S. Department of Energy, National Nuclear Security Administration, Nevada Field Office.
• Ernest Williams is a founding member of the Nevada Test Site Historical Foundation and the National Atomic Testing Museum. He is also a U.S. Air Force veteran and the former budget officer and engineering technician at the U.S. Department of Energy’s Nevada Operations Office.
The Sedan Crater was created in the former Nevada Test Site as part of the United States’ Plowshare Program – a research and development project created to explore the technical and economic feasibility of using nuclear explosives for peaceful purposes in industrial applications.
The U.S. Atomic Energy Commission, predecessor of the U.S. Department of Energy, conducted the excavation experiment using a 104-kiloton thermonuclear device detonated 635 feet underground. The explosion displaced about 12 million tons of earth, creating a crater 1,280 feet in diameter and 320 feet deep. The force of the detonation also released seismic energy equivalent to an earthquake with a magnitude of 4.75 of the Richter Scale.
Decades later on April 1, 1994, the Sedan Crater was officially added to the National Register of Historic Places. The Nevada National Security Site, formerly known as the Nevada Test Site, has also offered general interest tours of the Sedan Crater in past years to thousands of tourists from across the country.
Tickets to the roundtable discussion are $10 for general admission, $5 for students with valid IDs and free for museum members. For more information and to register for the event, click here.
Media may request credentials to attend the roundtable discussion. Requests for credentials should be submitted to Desiree Vontur at email@example.com by Friday, July 29.
