This Nova website asks the question: "Who were the first Americans, and where did they come from?" The site was designed to accompany a Nova program about America's Stone Age Explorers that aired on November 9, 2004. The site provides a transcript of the program; a brief article discussing the disappearance of many large mammals around 13,000 years ago; a photographic exhibit of 10 expertly-crafted stone Clovis tools from the Fenn Cache; a map that shows potential pre-Clovis sites in North America; and an interactive matching game that examines early human artifacts. The site also links to a brief, downloadable Teacher's Guide that includes a Program Overview, Classroom Activity, and Viewing Ideas.
