I think Killer meant say, iron, not gold.
The Mississippians had no writing system or stone architecture. They worked naturally occurring metal deposits, but did not smelt iron or make bronze metallurgy.
Anasazi. And yes, they did that with rock tools. Most of the metal Amerindians used was copper, and to the extent of my knowledge only Mesoamericans used it for weapons. They had copper axes, but they weren't as good as flint or obsidian. I've heard iron deposits are harder to come by in the Americas, although I may be mistaken, and the only metal they could get easily was not judged to be as valuable or useful as flint and obsidian.Which Indians when built that sort of city which is overhung by a rockface? Did they do that without metal tools?
