Lesquerella gordoni

This and Lesquerella fendleri can form large carpets of flowers on dry slopes in wet years. This species is generally taller, more upright, and less densely leafy than gordoni, but reliable identification requires microscopic observation of leaf trichomes. Lesquerella fendleri seems to be the more abundant of the two in New Mexico, especially on limestone.
