Skeptic magazine is snookered by enviro activists and guess who’s partially to blame:

Unfortunately, in our eagerness to find additional examples of the inappropriate intrusion of religion in American public life (as if we actually needed more), we accepted this claim by PEER without calling the National Park Service (NPS) or the Grand Canyon National Park (GCNP) to check it.

The whole thing (at HuffPo, natch) is here. In fairness, the folks at Skeptic do seem rightly furious about the whole thing.
