Rio Blanco Nuclear Test Site: 1973 Detonation of Nuclear Bombs
In 1973, the US Department of Energy conducted nuclear tests at Rio Blanco County, Colorado, as part of Project Plowshare to explore peaceful nuclear applications. The tests involved three 33-kiloton bombs aimed at natural gas production, ultimately deemed unsuccessful despite no detected radiation in subsequent monitoring.

The US Department of Energy detonated three nuclear bombs in 1973 at the Rio Blanco site, located north of Rifle, Colorado, under Project Plowshare. Each bomb, measuring less than 8 inches in diameter and over 30 feet in length, was placed at depths of 5,838, 6,230, and 6,689 feet below ground.
The objective was to explore peaceful uses of nuclear energy for natural gas extraction; however, the project is largely considered a failure. Long-term monitoring has shown no increases in radiation levels in the area since the tests were conducted. This historical event reflects the complexities and challenges of using nuclear technology for non-military purposes.
