Appalachia's New River was labeled "the second oldest river in the world" during the 1970s as part of a campaign to save the river from being dammed. Despite the absence of geomorphic evidence, the promotion of the superlative age of the river was so successful that they mythical label became reality in the minds of the region's populace. The "oldest river" thus became a popular or vernacular region, defined as one perceived to exist by its inhabitants. Sources of evidence for the current existence of the oldest river as a popular region include Internet references, which typically use the positive place image of the ancient stream to enhance the value of the river valley's attributes. Geography educators and students at all levels will benefit from class research projects aimed at identifying and understanding popular regions found near their educational institutions.
