There are a lot of earthen indian mounds here in the USA that are nothing more than low hills when seen from the ground. When they’re viewed from above we find that they’re animal shapes. They’re all across the midwest.
The only real difference is in scale but that can be explained by the fact that the Nazca makers didn’t have to deal with forests. Also there’s the fact that desert preserves these things better.
The Hopewell indians seem to have been especially active in making them.
I was not aware of this. I will google hopewell/mounds etc. and take a look!
"Today the mound building cultures go under the names of Cahokia, Adena, Hopewell, and a number of other names. A number of famous parks and sites today are attributed to the mound builders, such as Monks Mound in Illinois and Serpent Mound in Ohio."
