Fire in Angeles National Forest Above Azusa 100 Percent Contained [UPDATE]

UPDATE: AZUSA, CA — The brush fire in Angeles National Forest above Azusa has been full contained, Angeles National Forest wrote on Twitter. The cause of the so-called Burro Fire remains under investigation.

AZUSA, CA — A small brush fire that was started at a shooting range was holding at five acres and was 20 percent contained Saturday afternoon, officials said.

The fire started at the Burro Canyon Shooting Park at around 11 a.m. and soon grew to about five acres by early Saturday afternoon, U.S. Forest Service spokesman Nathan Judy said.

The fire was holding steady at five acres and 20 percent contained, he said.

"The forward progress has stopped and we're working on full containment," Judy said.

San Gabriel Canyon Road (Highway 39) leading to the forest and East Fork Road have been shut down, according to the Los Angeles County Sheriff's Department.

No structures have been threatened by the fire. The shooting range, however, was evacuated as a precaution. Nearby Crystal Lake have not been evacuated, but the roads leading there have been been closed.

Because of heat wave forecast for this weekend, forest officials raised the fire danger level in the Angeles National Forest from high to very high on Monday.

The cause of the fire has not been determined.
