If you're a US citizen traveling from Canada to California by land, you do not need a passport until Summer, 2008 (this may change, but is the revised date the Department of Homeland Security issued).

You do, however, need a government-issued photo ID (such as a drivers license) and a certified copy of your birth certificate.
