They are very old and very large. The people that made them never had the benefit of actually seeing their work. Who made them is actually up for debate. Nobody knows for sure.

[Adventure]

Kinda look like art form the Aztecs or Incas.

I recognize it, but don't know the name. Isn't it in Peru?

Edit: are it the Nazca Lines?

[jack]

Yes, they are in Peru.

Edit: Good job. You got it

[Mistery]

Congrats Adventure

Good job!

Sorry it took me so long. My PC was acting weird and I had to restart it.

I have no idea if this will be easy or hard.

[Mistery]

Ummm...
I have no idea, lol.

Is it used for measuring something?

[Adventure]

Yes, it is.

[Adventure]

Nope. But have to look through it to measure something. I probably have to look through it very soon, but then the modern version of it.

Nope.
