At 3:45 pm on 12 November 1970, on a beach near Florence, Oregon, a road engineer gave the signal and 1,000 pounds (450 kg) of dynamite went off under a dead whale. A few seconds later, it started raining blubber.

This is the true story of the exploding whale: a plan that looked fine on paper, a man who saw it all coming, a brand-new car and a TV crew who filmed every second of it. Fifty-six years on, the town still throws the whale a party.

A dead whale and a highway department

On 9 November 1970, a 14-metre (45-foot) sperm whale washed up dead near Florence, a small town on the Oregon coast. It weighed about 7 tonnes, and it smelled exactly as you’d imagine. Officials also worried that curious visitors might climb onto it and fall in.

Getting rid of it fell to an unlikely team. Oregon’s beaches were then looked after by the State Highway Division, which made a rotting whale, officially, a road problem.

After talking to the US Navy, the engineers came up with a plan. They would treat the whale like a boulder, blast it into small pieces and let seagulls and other scavengers eat the leftovers. What could possibly go wrong?

The man in charge was George Thornton, an assistant district highway engineer. He reportedly got the job because his boss was away hunting, and he admitted he wasn’t sure how much dynamite to use. He went with 20 cases.

The man who saw it coming

Watching from the crowd was Walter Umenhofer, a charcoal company executive who happened to be in Florence on business. He also had military training in explosives, and he did not like what he saw.

When a tractor rolled up with the 20 cases of dynamite, his verdict was short: “That’s gonna kill someone.” He thought the charge was far too big and in the wrong place. Nobody listened.

So Umenhofer did the sensible thing and stood further back than everyone else. He’d left his new Oldsmobile in a car park nearby. He had just bought it from a dealer whose slogan promised customers a whale of a deal.

Remember that car. It’s about to become part of the story.

3:45 pm: the day it rained blubber

About 100 people had gathered to watch from roughly 400 metres (a quarter of a mile) away. At 3:45 pm, the dynamite went off.

The beach erupted in a column of sand and whale about 30 metres (100 feet) high. Then gravity took over. Chunks of blubber came raining down on the crowd, and the people who had come to watch ran for cover. Reporting for Portland’s KATU television, Paul Linnman summed it up perfectly: “the blast blasted blubber beyond all believable bounds.”

One chunk, about a metre (3 feet) across, landed on Umenhofer’s new Oldsmobile and crushed its roof. Amazingly, nobody was hurt.

When the air cleared, most of the whale was still lying on the beach. The seagulls, the stars of the clean-up plan, never showed up, possibly scared off by the bang. Highway workers had to bury what was left.

Thornton, however, was pleased. “It went just exactly right,” he told the local paper that evening, apart from the hole the blast dug in the sand under the whale. Within months, he was promoted. And less than two weeks after the blast, the state’s insurer paid Umenhofer the full value of his car. A whale of a deal indeed. He later called it his one day of fame.

How a local news report went viral

Linnman and cameraman Doug Brazil filmed the whole thing for KATU. Then, for two decades, the story was mostly forgotten.

In May 1990, the American humorist Dave Barry wrote a newspaper column about the exploding whale. A shortened copy spread across early online bulletin boards, and plenty of readers thought it had just happened. Oregon’s transport department started getting calls about a whale that had been dead for 20 years. One of its spokesmen later called it the first story to go viral on the internet.

Then the video took off. By 2006, one study found it had been viewed around 350 million times. For the 50th anniversary in 2020, the original 16 mm film was remastered in 4K, so you can now watch the blubber fly in high definition. In 2023, the Eugene Emeralds, a minor-league baseball team, even played games as the Exploding Whales, and Linnman threw the first pitch at one of them.

Exploding Whale Memorial Park (yes, really)

Most towns would quietly forget a day like this. Florence named a park after it.

When the city asked residents to name its new riverside park, it received 124 suggestions and put nine of them to a public vote. Sensible options such as Dune View Park and Little Tree Park never stood a chance. Exploding Whale Memorial Park won 439 of the 856 votes, and the new sign went up in June 2020. The park looks out over the Siuslaw River and its historic bridge, and it even has a mascot: a cheerful, completely intact whale called Flo.

Every November, the town also marks Exploding Whale Day. In 2026, the 56th-anniversary celebration runs on 14 and 15 November, with a screening of the documentary Oh Whale, appearances by Linnman himself and a toast to the whale at 3:45 pm, the exact minute it went bang. The local museum even displays some of the whale’s bones.

Whales can explode all by themselves

Here’s the twist: a dead whale doesn’t always need dynamite. As the body rots, gas builds up inside it, and sometimes it simply bursts.

The most famous case happened in Tainan, Taiwan, on 26 January 2004. It took three cranes, 50 workers and more than 13 hours to load a dead sperm whale onto a lorry. While it was being moved through the city, it burst, spraying blood and guts over shopfronts, cars and passers-by. Again, nobody was hurt, though plenty of people needed a very long shower.

Oregon, meanwhile, learned its lesson. When 41 sperm whales stranded near Florence in 1979, nobody reached for the dynamite. Today, the state’s policy is simple: bury dead whales in the sand.

The moral of the story

The exploding whale has everything: a confident plan, an ignored expert, a flattened car and a town that turned its most embarrassing day into a holiday. If there’s a lesson, it’s this: when the man with explosives training says it’s too much dynamite, it’s too much dynamite.
