I think it's just a particularly yellow zonalis. I agree it's not marginalis. macnelli and macswaini have much more yellow than this. That kinda leaves zonalis as the only reasonable option.

Nice photo -
This is a female, and in your photo she is collecting pollen from the anthers of the
Phacelia
by using her mandibles and foretarsi. The pollen is subsequently ingested and stored in a 'crop', from which it will later be regurgitated into the nest cell. For taking nectar she'd have her suctorial proboscis extended into the corolla, and body position would be different.
Not sure at this point as to species, though I favor
macneilli
because of the sulphur yellow, rather than ivory on the closely related
marginalis
.
Do you have other photos?
