Mexico and Central America have plenty of ancient, monumental structures (e.g., Chichen Itza). But the continental US and Canada do not. Why?

Maybe not as elaborate or well preserved as you’re thinking, but the [Aztec Ruins in New Mexico](https://www.google.com/search?q=aztec+ruins+new+mexico&tbm=isch&ved=2ahUKEwjK55Xh6ICEAxUDMUQIHXOLB8UQ2-cCegQIABAA&oq=aztec+ruins+new+mexico&gs_lcp=CgNpbWcQAzIFCAAQgAQyBQgAEIAEMgYIABAIEB4yBwgAEIAEEBg6BAgjECc6CAgAEAgQBxAeOgQIABAeUN8LWKAnYK8paABwAHgAgAFgiAH3B5IBAjEzmAEAoAEBqgELZ3dzLXdpei1pbWfAAQE&sclient=img&ei=F6u2ZYqAF4PikPIP85aeqAw&bih=1205&biw=1440) and the [Montezuma Castle in Arizona](https://www.google.com/search?q=montezuma+castle+arizona&tbm=isch&ved=2ahUKEwjHhen-6ICEAxWZNEQIHRPlDW0Q2-cCegQIABAA&oq=montezuma+castle+arizona&gs_lcp=CgNpbWcQAzIECCMQJzIFCAAQgAQyBggAEAUQHjIGCAAQBRAeMgYIABAIEB4yBggAEAgQHjIGCAAQCBAeMgcIABCABBAYMgcIABCABBAYOgYIABAHEB5QpQRYlwVgmQdoAHAAeACAAZEBiAHuApIBAzEuMpgBAKABAaoBC2d3cy13aXotaW1nwAEB&sclient=img&ei=Vau2ZYeHIpnpkPIPk8q36AY&bih=1205&biw=1440) are pretty impressive.
