The thick, noxious smoke billowing out of a warehouse in Los Angeles has turned into a fixture in the city’s skyline for almost a week – with no end in sight.

A fire at “Big Bear,” a cold storage facility operated by Lineage in Boyle Heights, Los Angeles, California, U.S.A., caught on fire 17 June and has been burning for multiple days.

The fire, which started last week, has been burning for seven days.

Firefighters are still battling a blaze at a massive frozen-food storage facility near downtown Los Angeles six days after the fire started.

Lineage believes the fire started while contractors were conducting testing on a rooftop solar array, but the owner of that solar array says the cause remains under investigation.

Los Angeles Fire Department ground crews, hazardous materials teams and three water-dropping helicopters were deployed to the blaze.

The cold storage leader raised $4.4 billion, and now boasts a market value of $19 billion, according to Bloomberg.
