An archeologist recovers and interprets the artifacts of our past. Historic archeology may use written history to relate the traditional account of a person or event, oral history to recount the past by the people who lived it, and architectural studies to describe buildings or landscapes. Drawing on all of this information, the archeologist endeavors to reveal the intangible aspects of past human cultures that may not have been recorded in written history. Objects with known manufacturing dates can lend insight into when a site was occupied. Bones, seeds, and bottles can help reveal what people ate. Other artifacts can give information about what people were purchasing and what they were making. These objects may also be associated with oral history accounts of everyday life.
