About five years ago, a crack appeared in the ground in Michigan. It's 360 feet long, a couple feet across, and about six feet deep, and trees have been tilted at dangerous angles. When it happened, there was also a tiny earthquake and a weird loud boom sound. Scientists have been baffled about this crack ever since.

Sounds like the beginning of a science fiction movie, right? Maybe some crazy Yoopers are going to get super powers and begin destroying cities in a mad search for paczkis and beer! Or maybe some underground monsters will come out of the crack and try to destroy human civilization and reclaim the surface that was stolen from them millennia ago!

So far, none of that has happened. Maybe my mind is overly-imaginative.

There's just a big crack in the ground in a little place called Menominee, Michigan. If you don't know where that is (I sure as hell didn't), it's at the southern end of part of the weird fish northern chuck of the state. Not even on the mitten part of the state.

There are about 9,000 people in the town.

Even though there have been more booms coming from Wisconsin since this one, scientists have been scratching their heads trying to come up with an explanation for this crack.

Some sciency people think it could be a "pop-up", where rock layers shift after being weighed down by glaciers. Which is odd, since the glaciers moved house thousands of years ago, and usually pop-ups happen in quarries.

This is far from the final answer. The sciency people still don't REALLY know what this thing is, so I think I will stick with the whole "Crazy Yoopers with super powers" theory.

Hey, it could happen.
