Hi! Today is April Fools’ Day, which is perhaps the worst day on the internet. Instead of sharing something new (which you may think is a joke), I’m going with a re-run from 2012 featuring an incredible prank. Enjoy! — Dan

Dormant and Tired

Kruzof Island is in the North Pacific Ocean, one of many Alaskan islands that run down what would otherwise be the Canadian coastline, and not too far from the state capital, (Here is it on a map.) Juneau. Kruzof Island is home to Mount Edgecumbe, a dormant volcano stretching about 3,200 feet to its summit. Mount Edgecumbe is a tourist attraction — it makes for a manageable hike and is generally safe. The most difficult part about climbing the mountain is getting to it in the first place — Kruzof Island does not have a permanent human population, and therefore, there is no regular transport to the mountain. The closest town, Sitka, Alaska, is on a nearby island. To climb Edgecumbe, one typically leaves from Sitka.

In general, placing a city nearby a volcano is a bad idea, but Edgecumbe has been dormant for millennia — its last known eruption was over four thousand years ago. But in 1974, the town of Sitka got a scare. Edgecumbe, apparently, started to awake from its long, long slumber, as seen above. On the first day of April of that year, a plume of black smoke appeared, arising out of the top of the mountain. Conditions in the area were unusually clear, and people from Sitka could easily see the now-festering volcano. Was Edgecumbe no longer dormant?

The Coast Guard went to check, dispatching a helicopter to fly over the volcano’s crater and check for — well, who knows? What the helicopter pilot saw, though, was not an eruption. Rather, it was a message in the snow, spray painted in large black letters:

“APRIL FOOL”

Sitka was the target of an extravagant prank.

The prankster’s name was Oliver Bickar, better known as Porky to his friends and family. The middle-aged man came up with the idea in 1971 — three years earlier! — and started preparing. He collected dozens of old tires in an airplane hangar and waited. The conditions were near perfect on, coincidentally, April Fool’s Day 1974. He convinced some friends (and a helicopter pilot) to help him transport his collection of tires to the mountain’s summit, douse them all in kerosene, and light them on fire. He even went to the trouble of getting clearance for his prank from the FAA and local police — just to make sure that they didn’t get arrested for their harmless prank, and to make sure local officials could prevent a panic outbreak. (They forgot to or neglected to inform the Coast Guard.)

Not only did Bickar not get in trouble for his prank, but, as recounted by the Museum of Hoaxes, he actually got a lot of good press about it and positive reactions from locals. Even a Coast Guard admiral congratulated Porky on a prank well pulled.

The Supply Chain Crisis Is Escalating — But This Tech Startup Keeps Winning

Global supply chain chaos is intensifying. Major retailers warn of holiday shortages, and tech giants are slashing forecasts as parts dry up.

But while others scramble, one smart home innovator is thriving.

Their strategic move to manufacturing outside China has kept production running smoothly — driving 200% year-over-year growth, even as the industry stalls.

This foresight is no accident. The same leadership team that saw the supply chain storm coming has already expanded into over 120 BestBuy locations, with talks underway to add Walmart and Home Depot.

At just $1.90 per share, this resilient tech startup offers rare stability in uncertain times. As investors flee vulnerable companies, this window is closing fast.

More About Alaska and Pranks

Separately, that is.

Today’s Bonus fact: Juneau, Alaska is only accessible by air or sea — all cars and trucks in the city are brought in on barges or ferries. Road construction and maintenance are expensive given the environment of the area. None of Juneau’s roads leave the city.
