Thank you for your question. It appears to be a larva of one of the members of the long horned beetle family. California has several species of this insect, and, since they gravitate toward specific species of trees, knowing what type of wood you found it in would be helpful. But, without that information, here is a general discussion of these types of beetles in California:  https://www.everythingabout.net/articles/biology/animals/arthropods/insects/beetles/longhorned_beetl...

Hope this is helpful.

One of my insect ID friends suggests it may be the California Prionus root borer beetle, discussed here:  https://digitalcommons.usu.edu/cgi/viewcontent.cgi?referer=&httpsredir=1&article=1653&co...
