Fire crews were continuing to work Monday to establish containment lines around the San Gabriel Complex Fire, comprised of the Reservoir and Fish fires. The Reservoir Fire was human caused, according to a posting by officials, while the Fish Fire remains under investigation.

The main issue firefighters were facing is steep, rocky terrain, the Angeles National Forest's Andrew Mitchell told KPCC. Firefighters were fighting the fire mostly via hotshot crews dropping in via helicopter, with fire engines not playing much of a role, Mitchell said.

There was still no anticipated containment date.

"Every day presents a unique situation," Mitchell said.

Still, Mitchell said that firefighters were making great strides in containing the fire.

Firefighters are still dealing with high fire conditions, which Mitchell said has an effect on firefighters, making them more fatigued due to their heat and the gear they wear.

The winds didn't play a huge factor in containment, Mitchell said, with firefighters able to get a good grasp on building containment line and reinforcing structure protection.

The weather was also cooperating with firefighters, Mitchell said, with morning marine layer helping by adding extra humidity. It's allowed firefighters to get more containment and gain an advantage on the fire.

Mitchell also warned, with the Fourth of July coming up, that fireworks aren't allowed in the national forest and that anyone found with them would be cited and fined.
