An explosion rocked an outdoor area near the Hoover Dam on Tuesday as onlookers were on the site, some of them rolling their cameras.
Smoke billowed and alarms blared as a fire ensued in an exterior electrical area of the dam.
The Boulder City Fire Department arrived on scene after the fire had gone out. Details of the incident still sparse.
The Hoover Dam provides hydroelectric power for public and private utilities in Nevada, Arizona, and California. It’s unclear what impact this may have on electricity for the region, but with a summer heatwave underway, parts of the U.S. were already expecting potential blackouts even before this incident.
