Mount Edgecumbe Volcano Prank: The 1974 Porky Bickar Hoax 70 tires, a helicopter, and a legendary 50-foot 'APRIL FOOL' sign in the snow. Read how Porky Bickar pulled off history's greatest hoax.

Mt Edgecumbe (known as Lùx to the Tlingit) is home to perhaps the funniest volcano-related April Fools day joke in history.
A dude named Porky helicoptered 70 oil-soaked tires into the volcano’s crater, spray painted “April Fool” in the snow and then lit the pile ablaze.

One of the best parts of my job: writing recommendation letters for my incredible students. It’s so fun to reflect on everything they’ve accomplished and help them take their next step. Also, WAY easier to hype them up than write anything even remotely similar about myself 😆

I often see this comparison of glaciers on Svalbard posted without attribution. It’s from a whole series comparing photos taken by the Norwegian Polar Institute in 1928 and by Christian Åslund, a Stockholm-based photographer, in 2002. See the others here:
