This thread, about the oldest building in the US, got me thinking about the American Indian, about whom I know very little.
Why are there no American Indian buildings? The little I know (mainly from Westerns) depicts tepees as being the only form of habitation. Is this right? I believe that some American Indians practiced agriculture, which would suggest a settled society, which, in turn would suggest permanent buildings. But, a dominant image I have is of them being nomadic, following bison, which would explain the lack of buildings.
I know that there were many tribes, some of whom would not have interacted. But, in popular imagination at least, their cultures seem very similar. So why did all of them not use permanent buildings? For example, if there were tribes in Florida, I can’t see them hunting bison, and therefore not needing to be migratory.
I would have thought that it would be quite difficult for people covering the majority of a continent to leave so little permanent evidence of their existence.
