Rio Blanco Atomic Explosion Site

Field review by the editors.

Rio Blanco, Colorado

By the early 1970s the U.S. government was anxious to find some use for its surplus of nuclear bombs. Its friends in the petroleum industry had the answer: explode them underground to release natural gas! It would be a lot faster and cheaper than drilling.

On May 17, 1973, that's what the U.S. government did. Three 30-kiloton atomic bombs were blown up here, simultaneously, a little over a mile underground. The explosions released lots of natural gas -- but it was too radioactive to ever be used.

The project was abandoned, the shaft was sealed with cement, and a concrete marker and plaque now mark this remote site.
