Social media footage showed smoke coming from the ground near Idaho National Lab, which tests nuclear energy projects

Smoke has been seen rising from the desert area above the Idaho National Lab, which carries out nuclear energy tests.

The cause of the smoke is not yet known, but reporters from East Idaho News was on the scene. 

The INL nuclear facilities are located in the remote and sparsely-populated desert about 45 miles west of Idaho Falls, near the town of Arco. 

In 1949, the site was established as the National Reactor Testing Station.

Before the INL was established, the site was the Arco Naval Proving Ground, in use during World War II

Gun barrels from battleships like the U.S.S. Missouri were reconditioned at the Naval Ordnance Plant in Pocatello, 80 miles away, and then taken by train to the Naval Proving Ground.

The guns would be test-fired and scored, before being sent back to the Pacific Theater.
