Alyssum simplex for the other, maybe.

 

Astragalus lonchocarpus, I like this answer,thank you

 

Thank you, maybe
when I google for images, they look different but... it grows on stone

 

Can it be Physaria?

 

Perhaps, that is another option. The species of Physaria I looked at had different leaves, but I may have missed some.

 

Colorado Physaria
I think some leaves look the same as on my photo
