Need ID of yellow flowers and white flowers

This is an image of the desert near Phoenix. I need to identify the yellow flowers and the white flowers. I know the lavender ones are owl's clover.

 

Needs close-up photos, please! Can't see any detail of flower structure here.

 

My wild guess:
yellow: Balsamorhiza sagitata
white: Astragalus purshii

 

I'm sorry, but I don't have close-up pictures of the flowers.

 

Thanks! I'll look up the common names for these and see if they sound familiar.

 

Some other possible candidates:
yellow: Desert marigold (Baileya multiradiata) and Yellow cups (Camissonia brevipes)
white: Desertstar Daisy (Monoptilon bellidiforme)

 

I think those are right! At least the daisy one is, I think. I think yellow cups are larger than these flowers, but not sure of that, either. Thank you so VERY MUCH.
