Wildflowers: Wyoming Astralagus ID

Could you help me identify this wildflower. It was photographed in July just off of the Chief Joseph Scenic Byway in northern Wyoming.

I was thinking that it might be possibly crazyweed or some sort of Astralagus. Can you help me identify it?

 

Probably, Oxytropis - Oxytropis besseyi or Oxytropis lagopus.

 

Thank you. Oxytropis besseyi seems a good match (someone locally said it was a crazyweed, which I think might be the popular name for this.

I appreciate the help.

 

"Crazyweed" and "locoweed" are common names for Oxytropis and Astragalus in general.
