    The Greater Chaco Cultural Landscape holds deep cultural, spiritual, and historical significance to many Pueblos and Native American communities.

    Today, that incredible landscape is at risk.

    The Secretary of the Interior proposes to revoke the withdrawal of up to approximately 336,425 acres of public lands located within a radius of approximately 10 miles surrounding Chaco Culture National Historical Park (CCNHP) in San Juan County, northwestern New Mexico.

    Without this protection, lands outside the park boundaries could open to oil and gas development, risking irreversible damage to irreplaceable cultural sites and the broader landscape that gives them meaning.

    Public advocacy by supporters like you can make a difference, and public lands like the Greater Chaco Cultural Landscape need your voice now more than ever.

    Hurry! Following an initial 7 day comment period in April, the Bureau of Land Management has opened another 14-day public comment period, closing on July 29 at midnight Mountain Time.

    The Greater Chaco Cultural Landscape was named to the National Trust for Historic Preservation’s list of America's 11 Most Endangered Historic Places in 2011 and again in 2026 due to these significant ongoing threats.
