The Only Atomic Bomb Crater in the U.S. Open to Visitors

The incident occurred during a routine training mission when a mechanical error caused the bomb to fall from the aircraft. Despite the absence of a nuclear core, the conventional explosives within the bomb detonated upon impact, leading to a sizable explosion and extensive property damage.

The Gregg Family’s Ordeal

The bomb landed in the backyard of Walter Gregg’s home, approximately 50 yards from his garage. The explosion destroyed the house, injured six family members, and killed several of their chickens. Remarkably, the family survived with relatively minor injuries, and no fatalities occurred.

A Unique Historical Site

The crater site is located on private property, but visitors can access it with permission. A historical marker was erected near the site in 2008, and fragments of the bomb are displayed at the Florence County Museum, offering a tangible connection to this unusual chapter in American history.


Atmosphere & Décor

The site is situated in a quiet, wooded area, providing a serene setting for reflection. The natural surroundings contrast with the site’s historical significance, offering visitors a peaceful environment to contemplate the events that transpired here.


Other Considerations

Can I visit the site?
Yes, but the crater is located on private property. It’s essential to obtain permission from the landowner before visiting to respect their privacy and property rights.

Is there parking available?
Parking options are limited due to the site’s location on private land. Visitors should plan accordingly and ensure they have permission to park on the property.

Are there any facilities nearby?
The area is rural, and amenities are scarce. It’s advisable to bring necessary supplies, such as water and snacks, before visiting.

What is the best time to visit?
The site is accessible year-round. However, it’s recommended to visit during daylight hours for safety and to fully appreciate the historical context of the site.
