SAN FRANCISCO (AP) — Investigators have determined that target shooting sparked a fire that burned nearly 5 square miles in a San Francisco Bay Area wilderness park.
State fire spokeswoman Tina Rose said Thursday the news serves as a reminder that even the tiniest spark from a ricochet can grow into a massive fire.
The so-called Morgan Fire began near the town of Clayton on Sunday and spread to Mount Diablo State Park in Contra Costa County. It forced the evacuation of about 100 homes and spewed a plume of smoke, prompting air quality officials to issue health warnings for three neighboring counties.
The fire is 90 percent contained, with full containment expected Friday.
Rose says it has cost about $4 million to fight the fire.
