10. Michigan
Michigan might not be the biggest state when you only look at its dry land, but it’s a different story when you consider its water territory. This state has a massive amount of its total area covered by the Great Lakes. This makes it quite unique in how we measure its size.
Great Lakes Influence
When we talk about the biggest states by land area, we usually mean just the ground you can walk on. But for Michigan, a big chunk of its reported size comes from the water within its borders. This includes large parts of Lake Superior, Lake Michigan, Lake Huron, and Lake Erie. It’s kind of like how Alaska has a lot of land, but Michigan has a lot of water that counts towards its total area.
Size Comparison
Here’s how Michigan stacks up in terms of its total area, including the water:
| State | Total Area (sq mi) |
|---|---|
| Michigan | 96,716 |
This figure places Michigan as the 10th largest state in the U.S. when you include its significant water surface. It’s a good reminder that how we measure things can really change the outcome.
Interesting Facts
- Michigan is made up of two peninsulas: the Lower Peninsula and the Upper Peninsula.
