Okay kiddo, imagine a playground with a big hill. At the bottom of the hill there's a small river where you can find some rocks and maybe even some gold. The dirt that surrounds the river is called a gulch.
Now, let's say you want to search for some gold. So, you grab a shovel and start digging in the dirt of the gulch. As you dig deeper, you might find bigger rocks or sometimes even a small cave. You keep digging until you find something you're looking for.
A gulch is like a small valley or a ditch where a river flows through. People sometimes go there to search for gems, rocks or precious metals. It's like a little treasure hunt! But, be careful not to dig too deep or damage the environment. Always ask an adult for help and supervision!
