Four hundred firefighters battled a brush fire Saturday and Sunday that scorched 640 acres of mountainside in the Angeles National Forest between Mint and Bouquet canyons, north of Santa Clarita.

Dubbed the “Mint” fire, U.S. Forest Service spokesman Nathan Judy said it was reported Saturday at about 8 a.m. near the Agua Dulce Movie Ranch off of Mint Canyon Road, where the Forest Service set up a command post. None of the ranch property burned, Judy said. The blaze was limited to National Forest land.

The mountainous terrain made access difficult. On Saturday a combination of 26 fixed-wing aircraft and helicopters did most of the the heavy lifting – literally, scooping water from the Bouquet Reservoir and dropping it on the other side of the hill.

Forest Service choppers were also used to transport hand crews to drop zones close to the fire, Judy said.

Northwesterly winds in the early afternoon prompted sheriff’s deputies to put residents of upper Bouquet Canyon on alert, but no evacuations were ordered and no structures were threatened. The winds were expected to shift to a southwesterly direction in the early evening hours.

The Los Angeles County Fire Department assisted U.S. Forest Service firefighters. CAL FIRE, the Ventura County Fire Department and other agencies were rolling up to join the fight Saturday afternoon.

The fire was held in check Saturday evening and was 80 percent contained by 10 a.m. Sunday.

One firefighter sustained a minor injury Saturday. The cause of the fire is under investigation.
