(AP) - Officials say a wildfire in the backcountry of Yosemite National Park that forced the helicopter evacuation of about 100 park visitors nearly quadrupled in size overnight.
The wind-whipped fire had burned through about 2,500 acres as of Monday morning, up from about a square mile the previous night. Park spokeswoman Kari Cobb said it is not threatening any structures, and the park remains open. The fire, however, has forced the closure of trails to Yosemite's iconic Half Dome peak as well as a nearby campsite.
The visitors who were evacuated on Sunday included hikers who had climbed Half Dome. Cobb said officials were confident they had pulled everyone in danger out, but they would continue to look for anyone left behind.
Calm winds forecast for Monday along with relatively high humidity were expected to help with the firefight.
