Mount Edgecumbe is a dormant volcano near Sitka, Alaska, which was the subject of an April Fool’s Day hoax.
The volcano hasn’t erupted in almost 4,000 years, but in 1974 prankster Porky Bickar flew hundreds of tires into the crater and lit them on fire, tricking locals into thinking that the volcano was active again.
The Museum of Hoaxes reports:
Six years later when Mount St. Helens erupted a Sitka resident wrote to Bickar to tell him, “This time you’ve gone too far!”
