…By Sunday afternoon, the fire continued to grow west, with flames crossing Highway 32 near Butte Meadows.  …In Southern California, a fire in the Sequoia National Forest swept through the community of Havilah after burning more than 48 square miles in less than three days. The town of roughly 250 people had been under an evacuation order. Fires were also burning across eastern Oregon and eastern Idaho.
