What the act did
The Alaska Native Claims Settlement Act, signed into law on 18 December 1971, extinguished all aboriginal land claims in Alaska in a single legislative stroke. In exchange, the act conveyed approximately 44 million acres of land and nearly $963 million in compensation to Alaska Natives, distributed through a system of newly incorporated business entities — twelve regional corporations and more than 200 village corporations, with a thirteenth regional corporation added later to represent Alaska Natives living outside the state. Every Alaska Native alive on the date of enactment and enrolled in the system received shares in one regional corporation and, if affiliated with a recognised village, in a village corporation as well. The shares could not be sold for twenty years. The land and the money went to the corporations, not to individuals, and the corporations were organised under Alaska state law as for-profit businesses.
Before the act, the federal government had long treated Alaska Native land rights as unresolved. The territory became a state in 1959, and ANCSA — the act's widely used abbreviation — was partly the consequence of that transition: statehood triggered the state's own land selections, which collided with Native use and occupancy that had never been formally adjudicated. The discovery of oil at Prudhoe Bay in 1968 accelerated everything. A pipeline from the North Slope to tidewater required a right-of-way across land whose ownership was genuinely unclear, and the oil industry, the state, the federal government and Native organisations all had strong reasons to want clarity. The settlement that emerged in 1971 was a negotiated outcome among those competing interests, and it bore the marks of each.
How the architecture worked in northwest Alaska
NANA Regional Corporation was incorporated to hold the regional entitlement for the Iñupiat people of northwest Alaska — an area covering roughly 38,000 square miles centred on Kotzebue Sound and running north into the De Long Mountains. NANA received a share of the cash pool and made land selections across its region, including in the upper Wulik watershed. The Kivalina village corporation, like other village corporations within NANA's region, received a surface estate to land around the village itself; NANA, as the regional entity, held the subsurface rights beneath village corporation land throughout the region. That split — surface to the village, subsurface to the regional corporation — is a structural feature of ANCSA that has legal and economic consequences wherever minerals lie below the ground.

NANA holds land across the region and is a party to the mine agreement, which is why corporate structure and subsistence land use are the same conversation here. The regional corporation is a landowner and an employer
At Red Dog Mine, the consequences are direct. The orebody sits beneath land whose subsurface title passed to NANA through the settlement process. When the mine was developed in the late 1980s under an operating agreement with Teck Alaska Incorporated, NANA was the landowner at the table, not a permitting stakeholder. The arrangement that governs royalties, employment preferences and eventual mine ownership all flows from that title. Without the 1971 act creating NANA and vesting subsurface rights in it, the legal basis for that agreement would not exist.
The cash component of the settlement was distributed partly by regional corporation and partly by a revenue-sharing formula designed to prevent the wealthier, resource-rich regions from simply outpacing the rest. Seventy percent of mineral and timber revenues earned by any regional corporation were to be shared across all twelve original regional corporations, weighted by enrolled population. This provision acknowledged that the land conveyances were unequal in resource value and tried to distribute the underlying inequity, at least in part.
What the act left out and what followed
ANCSA extinguished not only aboriginal title but also aboriginal hunting and fishing rights, at least as a matter of federal law — a provision whose downstream effects proved contentious. The act was silent on subsistence in a way that created legal ambiguity for decades. Federal and state subsistence regimes developed separately and in parallel, generating a body of litigation and legislation that continued well past 1971. The act also imposed corporate structures on communities whose prior land relationships had been collective and customary rather than shareholding, a design choice that has been debated in Alaska law reviews and Native policy literature ever since.
The twenty-year restriction on selling shares expired in 1991, and Congress amended ANCSA in 1987 in response to concerns that shares would be sold out of Native ownership once they became freely transferable. The 1991 amendments gave corporations the option to extend alienation restrictions, authorised the issuance of shares to Alaska Natives born after 1971 (who had been excluded from the original enrolment), and introduced other modifications to protect the land base. Most regional corporations, including NANA, opted to continue restricting share transferability. The land itself remains in corporate ownership; it is not held in federal trust the way reservation land is in the lower forty-eight states.
Before the act, the federal government had long treated Alaska Native land rights as unresolved.
The ground this created
The legal landscape that ANCSA established is the ground — literally and administratively — on which every significant decision in the Wulik watershed sits. The road and port infrastructure of the DeLong Mountain Transportation System runs across NANA-selected land under easements and agreements rooted in the corporate title the act created. The monitoring obligations attached to the mine's permits are obligations on an operator working land that NANA owns. The relocation discussions for Kivalina involve a village corporation whose existence, land base and legal standing derive from the 1971 settlement.
ANCSA was not a treaty. It was a federal statute that extinguished one set of rights and created another, through corporate instruments, in a single legislative session. What it settled was the question of title. What it did not settle — the economic terms of resource development, the adequacy of subsistence protections, the long-run governance of corporate land — has been worked out, contested and renegotiated in the fifty-plus years since, deal by deal, amendment by amendment, across a region where the ground under the tundra turned out to contain one of the largest zinc deposits on earth.
