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.

Firefighters on Jan. 7 battled the raging flames of the Eaton Fire in Pasadena, California, where homes were burned to their bare skeletal structures.

A group of elderly people were seen being evacuated from a nursing home in wheelchairs by aides as the wildfires continued to spread through Los Angeles County. Video from Pasadena on Tuesday (Jan 7) shows at least nine elderly people being evacuated due to the threat of the Eaton Fire.

Some evacuated residents say their house still stands, but they can't get back to it to get more supplies. Authorities warn there is still a fire danger.
