Explosion at Electrical Transformer Rattles Colorado Foothills

An explosion at an electrical transformer rattled the foothills west of Denver early Tuesday near an old uranium mine, authorities said.

Jefferson County sheriff's deputies confirmed the explosion was in a transformer on a private road near the inactive mine, spokesman Jim Shires said.

There were no injuries and no reports of radiation, he said.

The department had received a report of a possible explosion in the area of the mine around 6:30 a.m. Flames could be seen coming from what appeared to be an electrical transformer, about 15 miles west of Denver.
