Long before 16th-century Europeans began to explore North America, the land was already home to an estimated 30 million people who spoke diverse languages and complex cultures. This legacy of language and inspired ideas is explored in this compelling North American Indian Cultures map. The map shows a broad sampling of linguistic families throughout the continent along with descriptions of each language group. A special inset highlights Native Americans innovations from parkas and snow goggles to new medicines and agricultural techniques. Coverage ranges from Central America to the farthest reaches of Canada and Alaska, as well as Greenland and the Caribbean Islands.
