Representatives from two dozen Pueblos, united in their unwavering resolve, joined New Mexico’s congressional delegation on Capitol Hill Wednesday to deliver a powerful, unequivocal message: "Chaco Canyon is not for sale." This urgent plea comes amidst renewed efforts by the federal government to dismantle a critical 10-mile protective buffer zone surrounding Chaco Culture National Historical Park, a UNESCO World Heritage site and a spiritual heartland for numerous Indigenous communities across the American Southwest. The proposed revocation of these protections threatens to open vast swathes of sacred land to oil and gas drilling and mineral extraction, igniting fierce opposition from tribal leaders, environmental advocates, and a bipartisan chorus of lawmakers.

For over a millennium, Chaco Canyon stood as the epicenter of a complex and sophisticated civilization, whose architectural marvels, intricate road systems, and advanced astronomical alignments continue to awe and inspire. The monumental Great Houses and kivas constructed by the ancient Chacoans between 850 and 1250 A.D. represent an unparalleled achievement in pre-Columbian North America, serving as a vibrant hub of ceremony, trade, and cultural exchange. Descendants of these ancient peoples, particularly the modern Pueblo tribes, maintain a profound spiritual and ancestral connection to Chaco, viewing it not merely as an archaeological site but as a living landscape imbued with their heritage, prayers, and identity.

U.S. Rep. Gabe Vasquez underscored this deep spiritual significance during Wednesday’s news conference in Washington, D.C., emphasizing that Chaco Canyon "is a vibrant place of prayer, pilgrimage and core to the identity of many Southwest tribes, whose connection to this land stretches back thousands of years. In other words, there is no replacing it." He condemned the administration’s decision to revoke protections for the greater Chaco landscape as an "absolute gut punch to New Mexico and to our pueblos," further decrying the mere 14-day public comment period as an "insult" to the democratic process and the sanctity of the land.

At the heart of the current controversy lies a Bureau of Land Management (BLM) proposal to rescind a landmark 2023 order. This previous directive, championed by then-Interior Secretary Deb Haaland – a member of the Laguna Pueblo and the first Native American cabinet secretary – withdrew approximately 336,404 acres of federal lands within the 10-mile radius of Chaco Culture National Historical Park from new oil and gas leasing and mining for a period of 20 years. Haaland’s order was a culmination of decades of advocacy by tribal nations and conservationists, aiming to safeguard the fragile cultural and environmental integrity of the region from the encroaching industrial footprint of the energy sector. The current administration’s move to overturn this protection aligns with a broader philosophy, echoing the previous Trump administration’s emphasis on "energy dominance" and deregulation, often prioritizing resource extraction over environmental and cultural preservation.

Supporters of the buffer zone have intensified their public outreach efforts as the truncated two-week public comment period on the environmental assessment for the proposed drilling and mining plan rapidly approaches its July 29 conclusion. This limited window for public input has drawn widespread criticism, with tribal leaders and lawmakers arguing it is grossly insufficient for a thorough review of the complex cultural, environmental, and socio-economic impacts that would result from increased industrial activity in the region.

Cochiti Pueblo Governor Phillip Quintana articulated the moral imperative at stake, posing a fundamental question: "What kind of legacy will we leave? Will we choose short-term extraction, or will we choose to protect one of the most important Indigenous cultural landscapes in North America, a place whose meaning reaches far beyond any single administration?" This sentiment encapsulates the core conflict between the immediate economic gains promised by resource extraction and the irreplaceable, long-term value of cultural heritage and environmental stewardship.

In a direct appeal to the federal government, New Mexico’s entire Democratic congressional delegation — its five senators and members of Congress — dispatched a letter to U.S. Interior Secretary Doug Burgum on Wednesday. The letter urgently requested an extension of the comment period to a minimum of 90 days, stressing the need for meaningful public engagement and a comprehensive assessment of potential harms. Furthermore, the delegation reiterated a previous commitment from Secretary Burgum, made during a June 2025 appearance before the House Natural Resource Committee, to visit Chaco Canyon. U.S. Rep. Teresa Leger Fernández, whose district encompasses Chaco, expressed profound disappointment, stating, "He lied," regarding the unfulfilled promise of a visit. She vowed to hold the Department of the Interior accountable to its own rules and regulations, asserting, "we will not let them silence us." Joey Sanchez, Chair of the All Pueblo Council of Governors, echoed this sentiment, revealing, "We asked for a meeting, but we never got it. I don’t know if you’re here in town, but you know we’re here. We’re ready to be with you. We ask you to come and visit." Secretary Burgum has yet to respond to these requests for comment.

The battle for Chaco is not confined to federal corridors; state-level officials in New Mexico are also mobilizing. State Rep. Derrick Lente, a Democrat representing Sandia Pueblo, has called upon Governor Michelle Lujan Grisham to assert New Mexico’s unequivocal opposition and to dedicate state resources to defending the landscape. Lente specifically urged the state Department of Cultural Affairs and the State Historic Preservation Officer to leverage their full authority within the federal review process, including their formal role under the National Historic Preservation Act, to ensure that the cultural harm posed by the proposal is honestly and thoroughly studied and weighed. A spokesperson for Governor Lujan Grisham confirmed the administration’s active engagement, stating she has been "pushing back on this terribly shortsighted and reckless proposal for months, including submitting official administration correspondence in April and coordinating with New Mexico’s congressional delegation to bolster our state’s official opposition."

While the Pueblos have presented a unified front against drilling near Chaco, the situation within the neighboring Navajo Nation, whose vast lands encircle the historical park, is more complex and internally debated. Navajo President Buu Nygren, who has publicly opposed the buffer zone, recently came in third in his primary election, meaning he will not return to office next year. However, the two leading candidates vying to succeed him have expressed similar views. Justin Jones, a prospective leader, has advocated for the rights of allottees – individual Navajo landowners holding specific surface and subsurface rights, often a legacy of late 19th and early 20th-century federal policies – to develop oil and gas extraction on their lands, citing their possessory rights. Similarly, Crystalyne Curley, the Navajo Nation Council Speaker, strongly disagreed with Secretary Haaland’s 2023 decision to impose the 10-mile buffer, reflecting concerns about economic sovereignty and resource control for Navajo citizens.

However, these perspectives do not represent the entirety of Navajo opinion. Mario Atencio, a Navajo activist whose family holds allotments within the buffer zone, has been a vocal critic of the oil and gas industry’s impact on his community. Atencio argues that revoking protections would grant the government "free rein to pollute the land," posing significant challenges and detriment to the public health of local residents. This internal divergence within the Navajo Nation highlights the profound economic disparities and complex land ownership issues that often intersect with environmental and cultural preservation efforts, particularly in regions where Indigenous communities have historically faced economic marginalization and limited opportunities.

The debate over Chaco Canyon transcends local politics, embodying a global struggle to balance economic development with the preservation of irreplaceable cultural heritage and the rights of Indigenous peoples. Chaco’s designation as a UNESCO World Heritage site places a global responsibility on the United States to protect its universal value for humanity. The potential for industrial encroachment not only threatens archaeological integrity and the spiritual practices of contemporary tribes but also raises critical questions about climate change, environmental justice, and the cumulative impacts of resource extraction on fragile ecosystems. As the public comment period dwindles, the voices from Chaco Canyon and its allies grow louder, demanding that this sacred landscape be safeguarded for future generations, unmarred by short-term gains. The legacy of ancient Chaco hangs in the balance, a testament to enduring cultural resilience and a call to protect what truly is priceless.
