The first image looks like the Californian type plants with narrower tomentose leaves. The other looks more like the typical Rockies form. The same kind of variation is seen in the shale-barren endemic P. antennarifolia.
Some Packera species have a large range of variation with local variants that may or may not be deserving of names. Even here in the eastern US I know that there are various populations (continuous in specific regions) that are distinct, but "fit" within the accepted species concept. Polyploidy seems to be common in the genus.
