It is not yet possible to reconstruct social patterns, since most of the remains consist only of shellfish middens and small, widely scattered campsites along the coast.
When the glacial cap retreated and valleys opened up, people (then existing as hunter-gatherers) began to follow the southward progression of game animals, fanning out across North America and down through Central America into South America, again a process occupying thousands of years.
Archaeological discoveries have unearthed human skeletal remains in association with now-extinct species of animals and in geological deposits of the last phases of the Ice Age.
