RIVERTON, Wyo. (AP) — An explosion at a natural gas compressor east of Riverton has injured one person.

The explosion happened Christmas morning. Fremont County Fire District Chief Craig Haslan says workers shut off the flow of gas to the compressor to stop the fire.

He says he didn't know the identity of the person injured.

The Associated Press reports workers were able to shut in the well before firefighters arrived and firefighters had the fire out by noon.
