(AP) -- Officials say the granite landscape in Yosemite National Park's backcountry is helping to naturally slow the spread of a wildfire.
Park officials say the rocky terrain has helped 400 firefighters who are battling the Meadow Fire from the ground and air.
The fire has burned more than 4,500 acres and is 10 percent contained.
On Sunday, the fire forced dozens of hikers to be evacuated by helicopter from Little Yosemite Valley and the park's iconic Half Dome.
Some backcountry trails remain closed, but the park's main entrances and other attractions are still open. Smoke from the fire has drifted to other parts of the park, though skies generally clear out in the afternoon.
