The document summarizes three First American tribes - the Cliff Dwellers, Mound Builders, and Aztecs. It provides examples of artifacts from the Mound Builders (mounds in intricate shapes) and Cliff Dwellers (cave drawings). Additionally, it incorrectly states that the Aztecs settled in Peru, when they actually settled in central Mexico, and the author would want to be a Mound Builder because they created large, uniquely shaped earthworks.
