Fire crews are working to keep a blaze in Yosemite National Park away from a grove of treasured giant sequoia trees.
Park spokesman Scott Gediman said Wednesday there was no imminent threat to Merced Grove.
The fire was about 10 miles away, and crews were reinforcing old containment lines to prevent it from getting to the trees.
Merced Grove is among three stands of giant sequoias in the park. The towering trees grow only on the western slopes of the Sierra Nevada and are among the largest and oldest living things on earth.
Gediman said about 50 homes remained under evacuation orders. The fire, which began on Saturday, has burned through more than 5 square miles. It was 34 percent contained.
