Archaeology of North America (Indians of North America S.)

"The Archaeology of North America" tells the fascinating story of how archaeologists investigate the orgins and prehistory of American Indians. More than 12,000 years ago, people we know as Paleo-Indians traveled from Siberia to Alaska across a land bridge that no longer exists. Archaeologists excavating at rock shelters and other sites across the continent have found many signs of the Paleo-Indian way of life, including the distinctive spearpoints with which these first Americans hunted giant game animals. Using tree-ring, radiocabon, and other dating methods, archaeologists can analyze the pottery and houses, tools and temples that they have uncovered. As a result, we know that the descendants of the Paleo-Indians and later migrants from Asia spread throughout the Americas.
