    No, it does not. Astragaluses are tough to identify and need seeing the pod structure and microscopic details of the pubescence.
    By just an overall look, it may be close to Astragalus piscator, rare plant in Grand County. As a second and third choices, Astragalus mollissimus and Astragalus sabulonum, species with more rounded leaflets.
