A Monrovia brush fire that at one point threatened 400 homes is now 85% contained, and all evacuation orders have been lifted, officials said.
No structures were damaged, and only one firefighter suffered a minor heat-related injury, said Jennifer McLain, a city spokeswoman.
Firefighters and handcrews will continue to work the fire through the evening, she said. Water-dropping helicopters remain on stand-by.
"The challenge is working in such steep terrain," she said.
The fire started about 11 a.m. Saturday and was sparked by a gardening tool being used for brush clearance at a residence in the foothills, she said. The blaze charred more than 100 acres and prompted fire officials to evacuate 15 streets.
"The fire came within 80 yards of some homes," McLain said. "We're very fortunate."
The fire prompted several bears in the San Gabriel Mountains to seek refuge in some residential neighborhoods, she said.
"We got seven different calls related to bears," she said, adding that animal control officers safely ushered the animals away from firefighters and other first responders.
