Moundbuilders of the Amazon

"Moundbuilders of the Amazon shows that sophisticated archaeological, bioarchaeological, and geophysical techniques of remote sensing are fully applicable to tropical sites. Additionally, the comprehensive use of such techniques by all archaeologists, doing fieldwork anywhere, could revolutionize archaeology, allowing archaeologists to look inside sites rather than simply excavate them.**Using a variety of remote sensing techniques, Roosevelt documents the existence of a major moundbuilding culture possessing monumental architecture and a rich artistic tradition on the lowland tropical floodplain of Marajo Island at the mouth of the Amazon River in Brazil, from about 400 A. D. to about 1,300 A. D.**Marajo Island at the mouth of the Amazon River is about the same size as Switzerland or Belgum. A well developed civilization existed there from about 400 A. D. to 1,300 A. D., comparable in many ways to the Inca civilization to the west or to the Aztec and Maya cultures to the north or, in some interesting ways, to the Pharonic cultures which developed at the mouth of the Nile. Because this civilization had no stone at its disposal, it expressed its monumental architecture in packed dirt which washed back into the alluvial floodplain long ago, effectively preventing archaeological discovery until the recent development of sophisticated techniques of remote sensing and reconstruction."--
