Firefighters battling the Colby Fire near Glendora and Azusa took advantage of cooler temperatures and calmer winds Saturday to make progress against the flames, authorities said.
The fire burning in the Angeles National Forest has consumed 1,863 acres and remained 30 percent contained Saturday, according to a statement issued by the U.S. Forest Service.
“Firefighters made excellent progress throughout the night taking advantage of the lower temperatures and favorable wind conditions to successfully perform firing operations and reinforce containment lines where possible while working in steep rocky terrain,” the Forest Service said.
The final mandatory evacuation orders were lifted for Mountain Cove residents at 6 p.m., according to the Los Angeles County Sheriff’s Department.
San Gabriel Canyon Road, which is above Mountain Cove, would remain closed, authorities said.
The blaze began Thursday near the intersection of Glendora Mountain Road and Colby Motorway, and left two firefighters and one resident with minor injuries.
An illegal campfire apparently ignited the flames, and fire officials cited drought conditions as contributing to the blaze.
Three men in their 20s were arrested and booked on suspicion of recklessly starting the fire, Glendora police Chief Tim Staab said.
A resident had called police to report two of the men “suspiciously” walking from the fire, Staab said; those two were arrested by police, while the U.S. Forest Service took a third man into custody two hours later.
The suspects were identified as Clifford Eugene Henry, Jr., 22, of Glendora; Jonathan Carl Jarrell, 23, of Irwindale; and Steven Aguirre, 21, a homeless man from Los Angeles.
