The National Parks Service (NPS) may be trying to stop an Arizona mining project by quickly and quietly creating a historical district on federal lands that would make such projects much harder to get approved. NPS doesn’t include any details on what land could be made into a historical district, which means ranchers, construction companies and even local governments that depend on access to Oak Flat are left in the dark about how their livelihoods will be affected by the listing. NPS proposed creating the “Chi’chil Bildagoteel Historic District” in Kearney, Arizona last June, but Gosar and Kirkpatrick quickly rebuffed the proposal, noting the name used by NPS does not appear on any maps.
