Visitors to Yosemite National Park are being asked to leave the Merced Lake, Sunrise and Vogelsang High Sierra Camps to allow firefighters to work.
Approximately 100 hikers were evacuated from the top of Half Dome, Little Yosemite Valley, and surrounding trails, via helicopter.
A wildfire burning inside Yosemite National Park has forced evacuations.
Crews are looking into whether this is tied to the Meadow Fire that was sparked by lightning back on July 20, park spokeswoman Kari Cobb said. For weeks, that fire stayed at about 19 acres, and crews were just monitoring and controlling it. But around noon Saturday, they believe the wind may have fanned the flames and started a new spot fire that has grown to approximately 700 acres.
Throughout the afternoon, 7 helicopters, an airplane, and ground crews worked to extinguish the fire. At this point, there is no word on containment.
The area, at 7,000 feet in elevation, features rugged terrain. Ground access requires a several mile hike to the area affected by the fire. Yosemite National Park firefighters are working with fire crews from Cal Fire, Sequoia-Kings Canyon National Parks, Mariposa County Fire, California Highway Patrol, and U.S. Forest Service. There are over 100 firefighters dedicated to the fire, with more resources en route.
There are no reported injuries or structures affected by the wildfire. The cause of the fire is still under investigation.
