Wildfire burns on Angel Island

SAN FRANCISCO, California (CNN) - A wildfire on San Francisco Bay's Angel Island burned out of control late Sunday, but none of the buildings at the historic state park have been damaged, according to a Marin County fire official.

The fire, which began about 9 p.m. (12 a.m. ET), covered about 100 acres of vegetation near the top of Mt. Livermore's 788-foot peak, Battalion Chief Mike Giannini said.

All of the park workers and campers on the island were safe, he said.

Angel Island - a hilly, grass and forest-covered island - is the largest in San Francisco Bay.

The island was used as a quarantine station for immigrants suspected of carrying diseases starting in the late 19th century.

It's now a place for hiking, biking, camping and boating.
