Wait, What?

Here's a headline you don't see every day: Mirages possible on Lake Michigan this week.

I mean, this entire year has seemed like a mirage, but this is the real deal. Of note:
Mirages over Lake Michigan typically appear upside down and above the horizon. These are known as “superior” mirages and were given their name because they float some distance above the horizon.

Often, they can be images of ships or even the buildings of Chicago, which typically aren’t visible from our shores.

If you're wondering how this is possible, it's related to hot air over cold water. In some situations, it can change air density enough to bend light waves.

Pretty astounding.

Pictures? Here's one:

If it was April Fool's Day, I wouldn't believe it.
