State, local and federal firefighters are battling a blaze that broke out near Pinecrest on Monday morning.
According to Veronica Garcia, spokeswoman for the Stanislaus National Forest, the fire was reported just after 6 a.m. along the east end of Beardsley Lake at Hell's Half Acre Road.
By Monday night, the fire had grown to 275. Earlier in the day, Garcia reported there was zero percent containment.
The cause had not been determined and was under investigation.
Crews from Tuolumne County, the U.S. Forest Service and the California Department of Forestry and Fire Protection were working the blaze, with two tankers and two helicopters providing help from above.
"We have a lot of resources on order," Garcia said. That means several teams from other areas are on standby, ready to head to the area if necessary. "Conditions continue to change, every minute, every second."
The area is fairly wild, with what Garcia described as steep and rocky terrain and a lot of brush and timber for fuel. No evacuations have been ordered, though residents have been notified.
The so-called Power fire has the potential to grow to 400 acres. If it continues to grow, the fire could threaten transmission lines in the areas.
"So far, it seems like the fire is going the opposite way," Garcia said. "We hope it continues to go that way."
Highway 108 is closed from East Old Strawberry Road to Clark Fork Road until further notice.
The fire was one of five wildfires active in California on Monday during a season that has been far more active than usual, thanks in part to a dry winter.
