The museum surveys the state's art, history, and natural wonders in three galleries of absorbing, detailed exhibits. You can travel through myriad ecosystems in the Gallery of California Natural Sciences, from the sand dunes of the Pacific to the coyotes and brush of the Nevada border. Kids love the lifelike wild-animal exhibits, especially the snarling wolverine and the big-eyed harbor seal. The rambling Gallery of California History includes everything from Spanish-era armor to a small but impressive collection of vintage vehicles, including a red, gold, and silver fire engine that battled the flames in San Francisco following the 1906 earthquake. Of particular interest in the Gallery of California Art are paintings by Richard Diebenkorn, Joan Brown, Elmer Bischoff, and David Park, all members of the Bay Area figurative school, which flourished here after World War II. Fans of Dorothea Lange won't want to miss the comprehensive collection of her photographs. On Friday evening the museum is a lively scene, with live music, food trucks, and half-price admission.
