Found this decently large spider on my porch here in the rural mountains of northern California, Sierra Nevada foothills. The picture is a close up but it’s about half the size of my palm including legs. Any ideas of what kind of spider it is?

Dear Christina,
This is a Trapdoor Spider.  It resembles this individual from the genus
Calisoga that is pictured on BugGuide.
