Why Chaco Canyon's Sacred Lands Face New Drilling

A thousand years ago, Chaco Canyon was the center of the world — at least for the ancestral Pueblo people who built its massive stone great houses, aligned them with celestial events, and connected them to outlying communities across the Colorado Plateau via an elaborate road network. Today, it sits inside a UNESCO World Heritage Site in northwestern New Mexico. Right now, the Trump administration is moving to open the land surrounding it to oil and gas drilling.

This isn't a hypothetical threat. It's a live regulatory process, and it's moving fast.

What Makes Chaco Different

Before getting into the policy mechanics, it's worth understanding why this particular fight generates such intense opposition — and why it's categorically different from other public lands energy debates.

Chaco Canyon isn't just historically significant in the academic sense. For the 19 Pueblos of New Mexico, the Navajo Nation, and other tribes across the region, the Greater Chaco landscape is a living cultural and spiritual homeland. The great houses, kivas, and road systems aren't relics — they're physical connections to ancestors and ongoing ceremonial life. Tribes don't merely want to preserve Chaco; they consider it inseparable from their identity as peoples.

The canyon itself is nominally protected as Chaco Culture National Historical Park. But "Chaco Canyon" and the "Greater Chaco Region" are not the same thing. The surrounding landscape — a patchwork of federal, state, tribal trust, and private lands — is where the drilling fight is happening. That region holds significant oil and gas deposits in the Mancos Shale formation, part of the San Juan Basin, one of the most productive fossil fuel basins in the American West.

The Trump Administration's Proposal

On Tuesday, the Trump administration initiated a 7-day Public Scoping period — a procedural step in the National Environmental Policy Act (NEPA) process — signaling its intent to advance drilling leases in the Greater Chaco Region. The scoping period is an early-stage mechanism where the federal government solicits public comment to define the scope of an Environmental Impact Statement (or, more minimally, an Environmental Assessment).

Seven days. For a decision of this magnitude.

That timeline alone tells you something about the administration's posture. Standard public scoping periods for controversial federal land decisions typically run 30 to 45 days. A 7-day window — particularly for a region with active Indigenous stakeholders who span multiple sovereign nations — functions less like genuine public engagement and more like a procedural checkbox.

The compressed timeline makes meaningful tribal consultation almost structurally impossible, and that may well be the point. Federal agencies are required under the National Historic Preservation Act and various executive orders to conduct government-to-government consultation with tribes on decisions affecting cultural resources. Whether a 7-day scoping window satisfies that obligation is a question that will almost certainly end up in court.

This proposal follows the administration's broader executive push to maximize domestic fossil fuel production across federal lands — a directive that has accelerated lease sales and environmental reviews across the West, often with reduced public comment windows and scaled-back environmental scrutiny.

The Economic Case and Its Limits

Proponents of Chaco Canyon drilling expansion point to genuine economic arguments. The San Juan Basin is estimated to hold billions of barrels of recoverable oil in the Mancos Shale. New Mexico's state government has become heavily dependent on oil and gas revenue — roughly a third of the state's general fund comes from energy extraction. More drilling means more royalties, more jobs, and more budget stability.

Those numbers aren't invented. They're real, and they matter for communities in the Four Corners region that have seen economic cycles driven by boom-and-bust energy markets.

But the economic calculus gets more complicated when you look at who actually benefits from drilling in the Greater Chaco Region versus who bears the costs. Many of the Navajo allotments and tribal trust lands in the region are already heavily impacted by existing oil and gas infrastructure — compressor stations, pipelines, flaring operations — that have been linked to elevated rates of respiratory illness and contaminated water sources in nearby communities. The populations living closest to the wells are often the same ones with the least political power to stop them and the fewest resources to relocate away from them.

Studies of the San Juan Basin have documented methane leakage rates among the highest in the country, visible from satellite imagery. Adding new drilling capacity to that basin without rigorous environmental controls doesn't just affect local air quality — it contributes measurably to national methane emissions at a moment when the U.S. has international commitments to reduce them.

What Drilling Means for Culture — and Law

There's a dimension to this debate that energy policy frameworks consistently undervalue: the legal and ethical weight of sacred land protection under existing U.S. law.

The American Indian Religious Freedom Act, the National Historic Preservation Act's Section 106 process, and the United Nations Declaration on the Rights of Indigenous Peoples (which the U.S. endorsed in 2010) all create obligations — some binding, some aspirational — around protecting sites of cultural and spiritual significance to tribal nations. Chaco and the surrounding landscape have been formally identified by tribes as Traditional Cultural Properties, a designation that triggers heightened scrutiny under federal historic preservation law.

Previous administrations took that scrutiny seriously. The Obama administration withdrew certain parcels near Chaco from leasing consideration. The Biden administration went further, issuing a 20-year moratorium on new oil and gas leasing within a 10-mile buffer zone around Chaco Culture National Historical Park in 2023 — a policy that the Trump administration is now working to dismantle.

Reversing a 20-year moratorium that was itself a response to decades of tribal advocacy isn't a neutral regulatory action. It's a statement about whose interests the federal government considers primary.

Tribal leaders from the All Pueblo Council of Governors have been unambiguous: the Greater Chaco Region cannot be treated as simply another resource extraction zone. The ceremonial roads, the outlier great houses, and the astronomical alignments embedded in the landscape — these aren't features that can be buffered with a 10-mile radius and called protected. The entire landscape functions as a cultural system.

What Comes Next

The immediate next step is the close of the scoping period and whatever environmental review follows. Given the administration's track record of expedited reviews, expect an Environmental Assessment rather than a full Environmental Impact Statement — a process that takes months rather than years and carries a lower bar for approval.

That's when litigation becomes the primary battleground. Tribal nations, environmental organizations, and historic preservation groups have successfully challenged drilling approvals in the Greater Chaco Region before, and the legal arguments — inadequate tribal consultation, failure to assess cumulative cultural impacts, violations of the National Historic Preservation Act — are well-established.

For developers and investors watching this space: federal energy projects in areas with active Indigenous legal claims carry real permitting risk. The Chaco Canyon drilling expansion may move quickly through executive channels, but the legal exposure attached to a project of this cultural sensitivity doesn't disappear because an administration wants it to. Courts have repeatedly demonstrated a willingness to halt or reverse approvals when proper processes weren't followed.

The deeper question this moment raises is one the energy industry has been slow to fully reckon with: as the U.S. pursues both domestic energy production and its stated commitments to Indigenous sovereignty, those two goals will increasingly collide on specific parcels of land. Chaco isn't an edge case. It's a preview of conflicts that will define federal lands policy for the next decade — whoever holds the White House.
