Devil's stovepipe

Devil's stovepipe is a cool word for something that looks like a big chimney. Imagine a big hole in the ground that is really deep, and it is shaped like a skinny tube. The hole is often made of rock or soil and is formed over a really long time by flowing water or an underground river.

Now, pretend that you are a curious explorer or adventurer who wants to take a peek inside the chimney. If you look down, you will see a long tunnel that goes straight down. Sometimes, the tunnel can be really dark, and you won't be able to see the bottom even if you shine a flashlight.

Now, you might be thinking, "Wow, that looks like a place where the devil would live!" But don't worry, it's just a name people gave to this type of hole because it's really deep and can look scary.

So, to summarize, Devil's stovepipe is a big chimney-like hole in the ground that goes really deep and is formed by things like water over a long time. It looks dark and can be a bit scary, but it's just a name people gave it, and there's nothing devilish about it.
