SAN FRANCISCO (AP) — Two wildfires burning in Northern California have expanded a bit but fire crews have made some gains and increased containment.

The blaze burning near the scenic Big Sur region of California has charred almost 73 square miles by Wednesday evening. It is 25 percent contained.

Officials are asking for the public's help to find whoever started the campfire that sparked the wildfire, which destroyed 57 homes. A bulldozer operator also was killed on the fire lines during a rollover accident.

A grass fire in a popular recreational area in Northern California has charred more than 7 square miles since igniting Tuesday afternoon. It spread quickly and prompted the evacuation of an RV and tent campground off Highway 128 near Lake Berryessa and the Napa Valley. No vineyards in wine country are threatened.

The fire is about 10 percent contained.
