Firefighters have made significant progress against the Washburn fire, which began July 7 in Yosemite National Park and has burned nearly 5,000 acres.
As of Monday, the fire had scorched 4,911 acres and was 50% contained, mostly within Yosemite.
Crews were working to build containment lines as they battled dry and hot conditions, with temperatures in the 90s, and heavy fuels.
