Danger Cave

It’s older than a log cabin. Older than a teepee, older even than the Great Pyramids. It’s a cave. People have been living in caves for thousands of years. Right here in Utah, even. And you know what? A cave works pretty well as a house—even though you might have to share it with bats.

Think about what your house does. Can a cave do the same things?

How would life in a cave be the same as life in your house? How would it be different?

Danger Cave is a big open cave near Wendover, Utah. People started staying in there at least 11,000 years ago (right after the Ice Age ended!)  They left stuff scattered on the cave floor. Over hundreds of years, many people used the cave, leaving their stuff on top of the old stuff.  When archaeologists excavated the cave, they found many layers of artifacts* and dirt—as deep as 12 feet down!

1. Okay, this was a giveaway question. The bottom stuff, of course! Next question.


2. 11,000 years ago. That’s a LOT older even than Great-Grandma Mabel! Next question.


3.  People liked sitting close to the outside instead of way back in the cave where it is dark and stuffy. And that’s where they left their trash. Next question.


4.  People didn’t figure out how to make pottery until about 2,000 years ago. Just like they didn’t  start making aluminum cans before 40 or 50 years ago. Next question.


5.  Early on, people used spears. After 2,000 years ago, people used bows and arrows. So the kinds of points they made changed. Next question.


6.  Thousands of years ago, a huge  lake—Lake Bonneville—had its shoreline at the level of the cave. Next question.


7.  They can learn more about what people ate. Next question.


8.  They were food! Next question.


9.  Besides seeds, they ate different kinds of animals. Next question.


10. Rabbit snares, nets, clothes, rope, and things like that. Next question.


11.  Anything we leave behind could be an artifact someday. (Note: This is no excuse for littering!) What do YOU think scientists will learn about us from our artifacts?


If you like the idea of learning about past people by studying their artifacts, maybe you'll want to be an archaeologist someday!
