A wildfire burning just east of Kings Canyon National Park has closed several recreational trails and required the helicopter evacuation of stranded backcountry hikers.

As of Monday morning, the Taboose Fire had burned 10,500 acres (16 square miles), the incident report from Inyo National Forest said. It was 10 percent contained.

The fire started Wednesday in sagebrush high desert eight miles south of the town of Big Pine, on Highway 395. The cause is under investigation, but is thought to have been lightning, the Inyo County sheriff’s office said.

On Saturday night, sustained winds of 40 to 50 mph accelerated its spread to the west and north, into the conifer forests on the Sierra’s eastern slope. Overnight, it jumped containment lines and grew from about 4,000 acres to more than twice that.

On Sunday, a helicopter belonging to Sequoia and Kings Canyon national parks was used to evacuate campers who had hiked to Red Lake, a mile east of the park boundary, and could not return because the fire had engulfed the trail. Four vehicles were destroyed at the Red Lake trailhead.

Evacuation orders have been issued for Baxter Ranch and Big Pine Canyon, including Glacier Lodge and Bernasconi Ranch, a science education camp and retreat center. The emergency shelter is at the fairgrounds in Bishop.

Closures as of Monday:

Tinemaha Campground

Red Lake Trail

Taboose Creek Trail

Birch Creek Trail

Tinemaha Road

Taboose Creek Road

McMurry Meadows Road

The communities of Aberdeen and Birch Creek were under evacuation warnings, and a public meeting was held Monday afternoon in Big Pine to update residents about the fire.
