The Eaton Fire burning through the hillsides and mountains above Pasadena is now approaching the Mount Wilson Observatory, with potential implications for both the historic structures and emergency communications during the ongoing wildfire siege devastating Los Angeles.

The blaze threatened the observatory and communications infrastructure at the peak. Later, an observatory official said it appeared to be under control.

Flames from the massive Eaton Fire are approaching the summit of California's Mount Wilson. The mountaintop is home to communication towers and an historic observatory.

At least 10 people are dead and many more injured as several fires broke out across Southern California amid historically dry and windy conditions.

The death toll from the multiple fires raging across Los Angeles County rose to 10 on Thursday night, as the largest of the five blazes—the Palisades Fire—grew to cover nearly 20,000 acres as strong winds meant the “Red Flag” fire weather conditions will remain in effect until Friday evening.
