Picher, Oklahoma, produced $20 billion worth of lead and zinc between 1917 and 1947. During both World Wars, half of all American bullets and bombshells were manufactured from Picher metal. The town’s population peaked at 20,000. By the time mining stopped in 1967, the miners had excavated 14,000 shafts, dumped 178 million tonnes of crushed, metal-contaminated rock — called chat — into mountains visible from the highway, and left 86% of the town’s buildings sitting on ground that the Army Corps of Engineers determined in 2006 could collapse at any moment. In 1994, a study found that 34% of the children in Picher had blood lead levels above the CDC threshold for concern. The EPA designated the area a Superfund site in 1983. The government offered buyouts. Most residents took them. An EF-4 tornado hit in 2008, killed six people, destroyed 160 homes, and eliminated whatever argument remained for staying. The municipality was officially dissolved in 2013. As of March 2026, what remains is a gorilla mascot statue celebrating the 1983 state football champions, a memorial plaque, a Quapaw Nation remediation office, and chat piles — grey, toxic mountains of mining waste that will take an estimated 50 more years to clean up. Of the 120 million tonnes of chat in the tri-state contaminated zone, roughly 10 million have been removed. The other 110 million are still there.
Centralia, Pennsylvania, has been on fire since May 27, 1962 — 64 years as of this writing. A borough council authorized the burning of a trash pit in an abandoned strip mine. The fire reached an exposed coal seam. The coal seam connected to the labyrinth of anthracite mines beneath the town. The fire spread underground and has never been extinguished. It burns at depths of up to 300 feet across an estimated 3,700 acres of underground mine workings. The Pennsylvania Department of Environmental Protection estimates it could continue burning for 250 more years — well into the 23rd century. Congress allocated $42 million for relocation in 1984. The governor invoked eminent domain and condemned every building in 1992. The Postal Service revoked Centralia’s ZIP code in 2002 — the town ceased to exist in the eyes of the mail system. As of 2026, fewer than five residents remain, living under a legal agreement with the Commonwealth that permits them to stay until they die, at which point their properties will be seized and demolished. Their homes will not pass to heirs. When the last holdout dies, the town will be physically empty — but the fire will still be burning.
Two mechanisms, one outcome
Picher and Centralia share a lecture in the Off The Map course because they represent the same category of territorial erasure — places removed from human habitation by the consequences of their own extraction economies — through two different mechanisms that both produce the same result: a municipality that functioned for decades, generated significant economic value, and was then rendered uninhabitable by the thing that had made it prosperous.
Picher’s mechanism is contamination. Lead and zinc mining created the town. Lead and zinc contamination destroyed it. The chat piles — the waste product of the process that generated $20 billion in ore — leached heavy metals into the soil, groundwater, and air. Children played on the chat piles. The high school track team trained on them. Residents used chat as fill for driveways and garden beds. The contamination was not an accident that happened to a mining town — it was the mining town’s normal operation, producing waste at a scale the town could not survive. The Quapaw Nation, which originally owned the land and leased it to mining companies under federal rules that restricted many Quapaw landowners from collecting royalties, has now partnered with the federal government to lead the remediation of a site that was profitably exploited on their land, with their resources, under rules designed to prevent them from benefiting.
Centralia’s mechanism is combustion. Coal mining created the town. An underground coal fire is erasing it — slowly, irreversibly, and on a timeline measured in centuries. The fire cannot be extinguished because the coal seam is too deep, too extensive, and too interconnected through the mine tunnels for any existing technology to reach. The options evaluated and rejected over the decades included flooding the mines (not enough water), excavating the burning coal (prohibitively expensive at an estimated $660 million in 1980s dollars), and trenching around the fire to cut off fuel (the fire had already spread beyond the feasible trench line). The fire won. The town lost. The mechanism is not contamination — the ground itself is the hazard, radiating heat, venting carbon monoxide and sulfur dioxide, and subsiding into mine voids that open without warning.
The holdouts
Both towns produced holdouts — residents who refused buyouts, rejected relocation, and remained in places the government had declared uninhabitable. The holdout phenomenon is the detail that connects Picher and Centralia to the Chernobyl exclusion zone, where the samosely — elderly self-settlers who returned illegally to radioactive villages — tend gardens in contaminated soil because the alternative (displacement) is, in their estimation, worse than the hazard. The holdouts of Picher and Centralia made the same calculation: the government says this place will kill you, but this place is home, and home is not a variable you solve for by moving.
Picher’s last known full-time resident, Gary Linderman, died in 2015. He had operated a motorcycle shop in the abandoned town, surrounded by chat piles and collapsed buildings, selling to customers who drove in from surrounding communities. He called himself and his neighbors “Chat Rats.” His death left the town without permanent residents for the first time since 1913.
Centralia’s five remaining residents are protected by a 2013 agreement that functions as a kind of biological sunset clause: they may stay until they die. The state cannot evict them. They cannot sell their properties. They cannot bequeath them. The properties will be condemned and demolished upon the last resident’s death. The holdouts’ occupancy right is, legally, a life estate with no succession — the rarest property arrangement in American real estate, created not by a will or a trust but by a standoff between a state government that wanted the land back and residents who refused to leave a town that is on fire.
The cleanup that doesn’t end
The rare earth and conflict minerals courses document supply chains where the extraction of value from the ground creates downstream consequences — environmental damage, armed conflict, health crises — that outlast the extraction itself. Picher and Centralia are the American domestic versions. The extraction is over. The consequences are permanent — or as close to permanent as the distinction matters.
Picher’s Tar Creek Superfund remediation has been ongoing for 43 years. The Oklahoma Department of Environmental Quality estimates another 50 years of work. The passive water treatment system developed by the University of Oklahoma removes 99% of contaminants from mine drainage — but a million gallons of polluted water still flow out of abandoned shafts daily. The residential contamination program costs $35,000 per property. The total remediation estimate is $600 million. Of the 120 million tonnes of chat in the tri-state zone, 10 million have been addressed. The math is not encouraging.
Centralia’s fire has no remediation plan. The fire is burning. The fire will continue burning. The estimated 250-year timeline means the fire will still be active in approximately 2276. The Pennsylvania DEP monitors gas emissions, maintains warning signs, and discourages visitors through a “Stay Out, Stay Alive” policy. The Battlefields of the Future course covers infrastructure designed to last decades. Centralia’s fire will outlast every piece of infrastructure currently standing on the planet. The fire will outlast the United States in its current form — if demographic projections, debt trajectories, or geopolitical volatility produce a different political arrangement in North America before 2276, the fire will still be burning underneath it.
The Silent Hill connection
Centralia’s cultural afterlife is more widely known than its actual geography. The town is widely cited as the inspiration for Silent Hill — Konami’s horror franchise set in a fog-shrouded, ash-covered abandoned town with fire burning underground. Konami has not officially confirmed the connection. The resemblance is sufficiently obvious that the confirmation is unnecessary. The Graffiti Highway — the abandoned stretch of Route 61, its asphalt buckled and cracked by underground heat, covered in decades of spray-paint — became Centralia’s most photographed feature and its most visited tourist attraction until the landowner buried it under dirt in April 2020. The burial was intended to stop trespassing. It also eliminated the only evidence visible from the surface that something was wrong — the cracked road that told arriving visitors the ground was not stable. The fire is still there. The visual evidence is buried. The metaphor writes itself.
Why they’re in the course
Picher and Centralia are the Off The Map case studies in self-inflicted erasure — territories that were removed from the map not by war, not by diplomacy, not by a patron’s withdrawal, but by the cumulative consequences of the economic activity that created them. Pripyat was erased by a reactor malfunction — a single catastrophic event. North Sentinel Island was never on the map. Transnistria is being erased by the withdrawal of patronage. Picher and Centralia were erased by the normal operation of their own industries, at the normal rate of their own waste accumulation, over the normal timescale of their own economic cycles. The extraction was not an aberration. The extraction was the town’s purpose. The town was the extraction’s byproduct, and when the extraction ended, the byproducts — the chat, the shafts, the coal fire — remained as the permanent residents that the human residents could not be.
The Ilemi Triangle is off the map because the border was never agreed. Azawad is off the map because the state is disintegrating. Picher and Centralia are off the map because the ground itself rejected continued human occupation — in Picher through contamination that poisoned a third of the children, in Centralia through combustion that will outlast the civilization that started it. Two American towns, both built on extraction, both destroyed by what they extracted, both still being cleaned up or burned through decades after the last residents left, both producing holdouts who refused to go — and both standing as evidence that the phrase “off the map” does not require a foreign country, a frozen conflict, or a disputed border. Sometimes it just requires a mine.
This is the kind of place our Off The Map course was built to map — where one town’s 14,000 abandoned mine shafts and 178 million tonnes of toxic chat will take 50 more years to remediate and the other town’s underground coal fire will take 250 more years to burn out, five residents are waiting to die so the state can demolish their homes, the last Chat Rat died in 2015 surrounded by mountains of lead waste in a town that made half the bullets America fired in two world wars, and the most visited feature of the burning town was a cracked highway covered in graffiti that the landowner buried under dirt because the tourists wouldn’t stop coming — and the fire underneath is still burning.
