Bolstered by more crews and aerial assistance, firefighters now have 25% containment of the Briceburg Fire, Cal Fire officials said Thursday morning.
Nearly 1,400 personnel are battling the wildfire near Yosemite National Park, which has spread to 4,900 acres.
In addition, eight air tankers and nine helicopters are involved in a suppression effort made difficult by steep terrain and gusting winds.
A day ago, the wildfire covered 3,600 acres and was 10% contained. The fire has destroyed one structure. There are no reports of injuries.
Cal Fire officials said Thursday morning that firefighters will remain focused on fireline construction and strengthening contingency lines.
