Mariposa County's 300-acre Bridge fire 65% contained

The Bridge fire in Mariposa County was 65% contained on Saturday evening.

The fire has burned 300 acres and has threatened 700 homes and five businesses, authorities said.

The blaze broke out about 12:40 p.m. Friday near the William Sell Bridge over the Chowchilla River Canyon, about a 15-minute drive northwest of Oakhurst.

The majority of the evacuations in the community of Ponderosa Basin were lifted at 7 p.m. Saturday. For residents living along the dirt section of Harris Road between Ponderosa Court and Highway 49, evacuations are still in place.

All roads leading into the community are closed and authorities said closures and continued security patrols are expected for the next few days.

There were 746 fire personnel working to extinguish the blaze Saturday. One firefighter received a minor injury on Friday and was treated and is now home, officials said.

The fire is moving southeast toward the Sierra National Forest, said Cal Fire spokeswoman Karen Guillemin-Kanawyer. The cause of the fire remains under investigation.

A second blaze that broke out Friday night near Oakhurst was quickly subdued. It was 4 acres and 50% contained Saturday -- firefighters continue to put out any smoldering spots, Guillemin-Kanawyer said.

Guillemin-Kanawyer said 95 out of 100 fires are caused by people -- which means they can be prevented. She shared some tips: When driving, make sure towing chains aren't hanging, which can ignite a spark while dragging along the pavement, and don't make a campfire close to dry vegetation.
