Some kind of argiope?

I looked at several photos online, and did not see anything with this dark abdomen. I did not take this photo, a friend posted it on facebook.
We wish your photo had more detail, but even then we often have difficulty identifying many Orbweavers to the species level. We do not believe this is an Argiope species, but rather, a member of the genus Araneus. Interestingly, BugGuide has a category under Araneus entitled “Dark California and Oregon with much white” and we would include your spider there.
