Tribal Trust Land Status in Cibola County, New Mexico

Ramah and To'hajiilee: two of the most checkerboarded Navajo chapters in the country

The Ramah Navajo Indian Reservation is a non-contiguous section of the Navajo Nation covering roughly 168,000 acres across west-central Cibola and southern McKinley counties, of which about 147,600 acres belongs to the Navajo Nation -- and it's documented as the most heavily checkerboarded Navajo chapter, with over 95% of its land area classified as off-reservation trust land interspersed with private, state, and other federal holdings rather than one contiguous reservation block. The To'hajiilee Navajo Chapter is a separate, similarly non-contiguous roughly 77,800-acre parcel spanning western Bernalillo, eastern Cibola, and southwestern Sandoval counties, sitting in a broader checkerboard area shared with Pueblo lands. For a buyer, the practical implication of both is blunt: in and around these chapter areas, a parcel's private, state, or trust status can change from one quarter-section to the next, and a map or listing showing a private-looking parcel near either chapter boundary is not evidence of its actual legal status.

Laguna and Acoma: leasing governed by tribal code, not case-by-case BIA approval

If your interest in land near the Pueblo of Laguna or Pueblo of Acoma involves leasing trust land -- for a business, a residence, or another purpose -- know that both Pueblos have moved under the federal HEARTH Act (the Helping Expedite and Advance Responsible Tribal Home Ownership Act) to adopt their own BIA-approved leasing codes, which let the Pueblo approve leases on its own trust land directly rather than sending each one through case-by-case Bureau of Indian Affairs review. Laguna's Business Leasing Ordinance (approved 2022) and residential Leasing Code (approved 2020) are both HEARTH Act-approved codes administered by the Pueblo's own Realty Program, which is also the office responsible for rights-of-way, service-line agreements, and land-use permits on Laguna trust land. This is a meaningfully different -- and often faster -- process than the standard BIA realty channel described for reservations without a HEARTH Act code, but it also means the applicable rules, forms, and approval authority are the Pueblo's own, not a federal regulation you can look up centrally; go directly to the Pueblo's Realty Program for current leasing terms rather than assuming a generic BIA process applies.

The Jackpile-Paguate Mine: an unresolved contamination legacy on Laguna land

A distinct and separate issue from groundwater contamination near Grants (covered on this site's companion well-water page) is the legacy of the Jackpile-Paguate Mine -- once one of the largest open-pit uranium mines in the world, operated from 1953 to 1982 on Pueblo of Laguna land near the village of Paguate, one of Laguna's six constituent villages. The mine disturbed more than 2,600 acres of Pueblo land, and while the mining company (Anaconda, later absorbed into Arco/BP) agreed decades ago to fund reclamation, current Pueblo officials and independent reporting describe reclamation as incomplete, with EPA investigations confirming ongoing releases of uranium, radium, and heavy metals threatening nearby streams and reservoirs. As of recent reporting, the site remains the subject of active federal court litigation over cleanup liability, with the operating company reported to be seeking a jury trial rather than settling. There is also renewed uranium exploration interest in and around the old mine footprint (including the Jackpile extension and nearby prospects), which is a live development worth tracking if you're evaluating land anywhere near Paguate or the broader Laguna reservation.

None of this means private fee land elsewhere in Cibola County is affected by Jackpile specifically -- the mine and the contaminated land are on Pueblo of Laguna trust land, not open to private purchase. But it matters for context (water and land near the Pueblo boundary can carry legacy environmental risk beyond just the Homestake site near Grants), and it's a useful reminder that "tribal trust land" in this county isn't a monolithic or static category -- it includes land with its own distinct legal, environmental, and economic history that a general land-status disclaimer doesn't capture.

What to actually check

1. Get a title search from the Cibola County Clerk/Assessor confirming the parcel is recorded fee land on the county tax rolls, not trust or allotted land -- especially important near the Ramah or To'hajiilee chapter boundaries given how finely checkerboarded that land is.
2. For any lease, right-of-way, or land-use request touching Laguna or Acoma trust land, contact that Pueblo's own Realty Program directly rather than assuming a standard BIA process applies, since both Pueblos administer their own HEARTH Act-approved leasing codes.
3. For anything near the Navajo Ramah or To'hajiilee chapters, contact the BIA Southwest Regional Office (Division of Real Estate Services, Albuquerque) for allotment and rights-of-way questions specific to that chapter, since Navajo chapter land generally runs through the standard BIA realty channel rather than a chapter-specific leasing code.
4. If a parcel is anywhere near Paguate or the broader Laguna reservation boundary, ask directly about any documented environmental legacy or active remediation/litigation tied to the Jackpile Mine site before assuming groundwater or surface conditions are unaffected.
5. Don't treat 'near a Pueblo or reservation' as one uniform category -- Acoma, Laguna, Zuni, Ramah, and To'hajiilee are five separate sovereign or semi-sovereign jurisdictions here, each with its own land office, leasing rules, and current issues.
