I don't know what phase this would be called (I'm waiting for hubbs book as well) but this is Antioch, CA locale -

It's not as brows as the So Cal coastals, the bands are not as clean as the Desert, but it has no yellow in the bands.
Here are my two male Redding, CA males - you can only see one head, but it is two snakes. Raised together, brumating together, will be separated after brumation.
I hear I'm lucky they didn't try to eat each other yet - I'm not going to push my luck with them not fighting now that they are sexually mature once they come out of brumation.

Like the Antioch, CA locale - they are not as chocolate brown as the So Cal coastal banded. They also do not have yellow in their bands. The bands appear to be cleaner than the Antioch, CA locale - but still not as clean as a Desert Banded.
According to Hubbs - as you go north from Redding they get even darker base color until they are true black pattern (like some of the desert kings).

Speaking of locality features with banded - I need to look at more northern locality snakes to be sure, but I think there is a difference in the underside of the tail that is locality specific. It seems that a lot of southern california snakes have completely black bottoms to their tail for about 2/3 of the tail from the vent before tail bands appear - while northern california banded have bands that break the black fairly quickly after the vent.
Hopefully I find a good number of Redding, CA kings this year so I can photograph that feature before release and see if it is the case.
