San Bernardino National Forest officials said Thursday the Hathaway Fire in the San Gorgonio Wilderness east of Banning has grown to 3,326 acres and is 40 percent contained.
More than 1,400 firefighters from federal, state, county and Native American agencies are working to create containment lines around the wildfire, which started Sunday in the northern part of the Morongo Indian Reservation.
Zac Maring normally works in the Sequoia National Forest, but he's helping out on the Hathaway Fire as a spokesman.
"Today (Thursday) there were two more crews than there were Wednesday, so the number of hand crews we have on the fire at this time is 43," said Maring.
San Bernardino National Forest Service officials said the fire is burning in a steep, remote area that is difficult to access, with a significant amount of dead trees because of the 1999-2004 drought and bark beetle infestation.
Maring said the estimated cost of fighting the wildfire so far is about $4 million.
