Full suppression efforts are underway. Two 20-person Type-1 hand crews are on scene. Four air tankers and two helicopters are also assisting. Temperatures are expected to drop tonight which should help firefighting efforts. The cause of the fire is under investigation. Smoky conditions are likely to persist over the next few days.
Trails on the north rim of Yosemite Valley south of the Tioga Road and east of Yosemite Creek, to near Olmsted Point, are closed.
