Amarillo, Texas: The Gas That Wouldn't Burn
From 1929 to 1943 nearly all the world’s helium came from one plant outside Amarillo, Texas — the gas that lifted the convoy blimps.
Three stories posted across one week in September 2026 — ten Cadillacs buried nose-first beside Route 66, the Panhandle plant that furnished the world’s helium and the shipment Washington refused to send Germany in 1938, and the 1968 monument whose four time capsules hold a ten-dollar bankbook until the year 2968. Each part below is the full post as published, with the reel it accompanied.

QUICK FACTS — THE HELIUM CAPITAL OF THE WORLD
› 1868: helium is discovered in the spectrum of the sun by Pierre Janssen and Norman Lockyer — named for helios, the sun — 27 years before anyone found it on earth
› November 11, 1926: Route 66 is commissioned; it turns one hundred this November. The buried Cadillacs run 1949–1963, the tail fin peaking on the 1959 models
› April 1929: the Bureau of Mines opens the Amarillo Helium Plant on a twelve-mile pipeline from the Cliffside field — almost all the world’s helium until 1943
› 1937–1938: the export ban is loosened and 18 million cubic feet is approved for Germany; after the Anschluss the Interior Secretary refuses to release it. The Hindenburg had flown on hydrogen
› 1943: a second Panhandle plant opens; helium lifts the Navy’s convoy-escort blimps
› After the war: surplus helium is pumped back into Cliffside as the national reserve; the federal helium program is sold to private hands in January 2024 amid recurring world shortages
› Helium today: MRI magnets, rocket-fuel pressurization, welding, deep-sea breathing gas — and balloons
› 1968: the Helium Centennial Time Columns Monument — four helium-sealed capsules opening in 1993, 2018 (resealed to 2093), 2068 and 2968; airlifted across town by helicopter in 1982
Part I — Mon Sep 21, 2026 · Ten Cadillacs, Nose-Down
Ten Cadillacs, nose-down in a Texas wheat field. On purpose.
In 1974 an art collective buried ten Cadillacs nose-first in a wheat field west of Amarillo, in model-year order, 1949 to 1963.
In 1974 a San Francisco art collective hauled ten used Cadillacs into a field west of Amarillo, dug ten holes, and tipped each car in nose-first. Nobody was selling anything. That was the whole idea.
The cars stand in model-year order, 1949 to 1963, so the row reads like a flip-book of the American tail fin: it sprouts, swells to full rocket-ship absurdity by the end of the fifties, then shrinks back toward nothing. Most came out of junkyards for a couple hundred dollars apiece. They all face west along old Route 66, tilted at an angle the builders said they borrowed from the Great Pyramid of Giza.
Then the visitors showed up with spray paint, and nobody stopped them. Half a century on, the factory colors are somewhere under a crust of paint thick enough to round off the chrome. Every masterpiece lasts until the next carload pulls in. Bring a can. That’s the custom.
In 1997 Amarillo itself had crept too close, so the whole row was dug up and replanted two miles farther west. Same order, same tilt. The city has been creeping toward it again ever since. Route 66 turns one hundred this November, and Cadillac Ranch is still its strangest mile marker.
It’s the most photographed thing Amarillo ever put in the ground. It isn’t the strangest.
The strangest, a foreign government once asked for. Washington said no: Part II.

Part II — Wed Sep 23, 2026 · The Gas That Wouldn’t Burn
Germany asked for Amarillo’s gas. Washington said no.
The Amarillo Helium Plant furnished almost all the world’s helium from 1929 to 1943; in 1938 Washington refused to sell Germany its gas.
In the 1930s the great passenger airships crossed the Atlantic on hydrogen, because the one gas that could lift them safely came from one country. And for fourteen years, nearly all of it came from one plant on the Texas Panhandle.
Helium was first spotted in 1868, in the light of the sun. On earth it hides in natural gas, and the gas in the Cliffside field northwest of Amarillo was unusually rich in it. The federal Bureau of Mines secured the field, ran a twelve-mile pipeline, and in April 1929 started up the Amarillo Helium Plant. The method: chill natural gas to about 300 degrees below zero until everything else turns liquid, then draw off what’s left. What’s left is helium.
From 1929 until 1943, the state historical marker says, that plant furnished almost all of the world’s supply. Congress had already declared helium a defense material in the 1920s and barred its export. So Germany’s airship builders, who wanted the gas that wouldn’t burn, designed for hydrogen instead.
In 1937 the law was loosened, and a sale of some 18 million cubic feet to Germany was approved. Then, in March 1938, Germany annexed Austria. The Secretary of the Interior refused to release the gas. The cylinders stayed in Texas.
When war came, a second Panhandle plant opened in 1943, and helium lifted the Navy blimps that escorted Allied convoys. Afterward the government did something only Amarillo would find normal: it pumped the surplus back underground at Cliffside and kept it there for decades as a national reserve. The federal helium program ran from Amarillo until its sale to private hands in 2024.
For fourteen years, if it floated and didn’t burn, it almost certainly started here.
In 1968 Amarillo built the gas a monument, sealed something inside, and left instructions not to open it for a thousand years: Part III.

Part III — Sat Sep 26, 2026 · Do Not Open Until 2968
Do not open until 2968.
The 1968 Helium Monument holds four time capsules sealed in helium, opening in 1993, 2018, 2068 and 2968 — with a $10 passbook inside.
In 1968 Amarillo, by then billing itself the Helium Capital of the World, marked the hundredth anniversary of helium’s discovery with a six-story stainless steel monument. Then it filled the columns with 1968 and welded them shut.
There are four columns, and each one is a time capsule: books, documents, films, seeds, office supplies, and one dehydrated apple pie. Once they were loaded, the caps were welded on and the contents sealed in a helium atmosphere. The gas does for paper what it did for airships. It refuses to react.
The columns open on a schedule: 25, 50, 100, and 1,000 years. The first came open on time in 1993. The second opened in September 2018, was emptied, refilled by the town, and resealed until 2093. The third waits for 2068. The fourth waits for 2968.
Inside that last one is a bank passbook showing a $10 deposit made in 1968. Depending on whose compounding you trust, it will be worth a quadrillion dollars or a quintillion, assuming the bank, the dollar, and Amarillo are all still in business.
Even the monument has traveled. In 1982 a helicopter lifted all six stories from its original spot beside Interstate 40 and flew it across town to where it stands today. It also works as a sundial, in case anyone in 2968 needs the time.
The Cadillacs took fifty years to vanish under spray paint. The bankbook has 942 to go. Amarillo is patient.
Cars, gas, and a ten-dollar bet on the year 2968.
