At least 116 homes and other structures have been destroyed by a California forest fire near Yosemite National Park, officials said Thursday.

The Oak Fire in Mariposa County has charred more than 29 square miles of trees and brush, with 39% containment, Cal Fire said in an incident update.

Assessment teams are moving through remote communities in the Sierra Nevada foothills looking for more damage.
