All Pueblo Council of Governors leaders announced that the Greater Chaco Cultural Landscape in northwestern New Mexico was named one of America’s 11 Most Endangered Historic Places for 2026 by the National Trust for Historic Preservation. The designation focuses attention on Chaco Canyon’s ancestral Pueblo sites and the cultural landscape that stretches across public and tribal lands, while tribal leaders, conservationists, and federal agencies weigh how to protect this sacred terrain.
The designation is a spotlight more than a shield, and that’s exactly what tribal advocates hoped for. For generations the All Pueblo Council of Governors has argued that Chaco and its surrounding landscape are living places of spiritual and cultural importance, not just archaeological exhibits. That cultural urgency contrasts with economic pressures like oil and gas leasing, which continue to gnaw at the corridors and viewscapes that make Chaco distinct.
Chaco Canyon and the Greater Chaco Cultural Landscape hold enormous archaeological and astronomical legacy. Massive great houses, roads that radiate outward, and alignments tied to the sky draw scholars, tribal elders, and visitors who all see the same marvel from different angles. Preserving those physical and visual connections requires more than plaques and markers; it needs land-use changes and long term stewardship that respect tribal voices.
Federal agencies including the National Park Service and the Bureau of Land Management play a central role because much of the landscape sits on public ground. The National Trust listing raises the political temperature, nudging agencies toward stricter review of new energy projects and toward stronger cultural resource protections. Still, the listing itself does not stop drilling or guarantee funding, so advocates are pushing for concrete policy moves.
Tribal leadership has framed the issue as one of sovereignty and cultural survival, calling for management that centers Pueblo and other Indigenous priorities. That means more say over permitting, better monitoring of impacts, and enforcement that respects traditional uses and sacred places. Cooperative management models are already being tested in other parts of the country, and many leaders see that path as the most practical way forward here as well.
Energy development and related infrastructure are the most visible threats, slicing viewsheds and increasing traffic and noise close to sensitive sites. Cumulative impacts are especially destructive; a single well can seem minor, but dozens reshape how people experience and care for the land. Beyond drilling, climate stress and recreational overuse also accelerate damage to fragile ruins and the soils that preserve them.
Public attention from the National Trust can help mobilize dollars for conservation, documentation, and community-led programming. Grants can support tribal archaeologists, cultural monitors, and restoration projects that keep knowledge alive and ensure younger generations can visit and learn. The designation also helps translate obscure technical reviews into plain-language narratives that voters and elected officials can understand and act on.
Still, any shift toward protection will need political will in Santa Fe and in Washington, where decisions about leasing and federal land management are made. Lawmakers and agency heads face competing pressures from industry and from communities who see tourism and stewardship as long-term, sustainable futures. Effective protection will likely combine local stewardship, state policy tweaks, and federal safeguards that limit the most destructive land uses.
What comes next will depend on follow-through. The All Pueblo Council of Governors and allied groups can use the National Trust listing as leverage, but turning attention into policy takes strategy, funding, and continued public pressure. Chaco’s stones have weathered centuries; whether the modern legal and political systems can match that endurance is the urgent question now.
