A wildfire that spread over hilly terrain in a rural area a few miles east of San Diego Zoo Safari Park, blackening 49 acres, was fully contained Sunday, according to the San Diego Fire-Rescue Department.

Crews left the scene of the Academy Fire on Sunday after doing mop-up work the day before, an SDFD official said.

No injuries or structural damage were reported.

The blaze erupted for unknown reasons at about 2:30 p.m. Friday off the 17700 block of San Pasqual Valley Rd, just south of San Pasqual Academy, Cal Fire reported.

Within 45 minutes, the eastward-moving flames were posing an “immediate” threat to at least one structure — an outbuilding — as ground crews and personnel aboard air tankers and water- dropping helicopters fought the fire.

By 4 p.m., personnel had significantly subdued the blaze and were getting close to halting its spread, Cal Fire Capt. Mike Cornette said.

There were no reported effects from the fire on the operations of the popular northern San Diego wild-animal park down the road from the burn zone.

Crews had the growth of the blaze halted as of 6:30 p.m. Saturday, according to the San Diego Fire-Rescue Department.
