Okay kiddo, have you ever heard of the word 'midden'? No? Well, a midden is like a big pile of stuff that was left behind by humans or animals. Think of it like a huge garbage dump, but not as stinky.
Now, let's think about humans. Sometimes we throw things away, like apple cores or empty cans, right? Well, imagine if we did that for hundreds or even thousands of years! That's how old some middens are.
Scientists and archaeologists study middens to learn more about the people who lived a long time ago. They can find out what they ate, how they made their tools, and even how they took care of their homes. All by looking at the things they left behind in the midden.
So, even though a midden may seem like just a pile of old stuff, it can actually teach us a lot about the past!
