On Wednesday, the U.S. Coast Guard said the California fire had grown to more than 30,000 acres.
The agency said it has declared a statewide emergency.
The Coast Guard reported the fire broke out on Wednesday and was burning along the coastline from the San Francisco Bay area to the ocean.
The fire started in the San Luis Obispo River near Bancroft, where it’s being controlled, said the Coast Guard.
The river has a major flow and is a major source of food for many of the animals that live along its banks.
The area is near the California State University of San Bernardino, the Santa Barbara County Museum of Natural History and the California Institute of Technology, according to the Coast Fire Protection District.
The district said the fire was still burning at 6 p.m.
The fire has been contained to about 10,000 square miles.
The county reported more than $2 million in property damage and $1.2 million total in insured losses.
The cause of the fire remains under investigation.
