Once upon a time, long, long ago....

Ha. You get the idea. It all happened a mere 420+ million years ago, but once upon a time Maine had some of the biggest volcanoes anywhere. And, they also produced some of the biggest eruptions in history. The likes of which man has never witnessed.

As the east coast was forming, there was a series of mega-eruptions that caused massive deposits of lava and ash up and down the coast, according to LiveScience.com. The most visible example being Isle au Haut in Acadia National Park. After it's eruption, it left thick, immense piles of volcanic debris, which has since turned into rock, obviously.

But the volcanic layers on Isle au Haut are over three miles(!) deep, with a layer of ash on top that is over 3200 feet thick. So this explosion caused enough material to be displaced in this one region, so as to cause a nearly 4 mile thick crust on the Earth! That's the equivalent of driving from one side of Bangor to the other side of Veazie.

Now, these volcanoes are dormant, meaning they have basically no chance of erupting. In fact, on Isle au Haut, the volcano's magma chamber is laying on it's side. And over millions of years, tectonic shifts have pushed to super volcanoes apart and exposed most of their leftovers, as opposed to secretly waiting to explode as some speculate may happen at Yellowstone someday.

So please... don't start calling your insurance company and try to get volcano eruption insurance. We're going to be fine. But the fact that once upon a time, Maine's volcanoes pretty much could've taken out the whole United States as we know it, just lends credence to how awesome we are. Why?

Because volcanoes!
