First published in 1855 and long out of print, The Antiquities of Wisconsin remains invaluable as a detailed record of many Indian mounds that were later destroyed by farming, development, or looting. Lapham was among the first scientists to produce evidence that the earthworks had been built by the ancestors of modern Native Americans, not some mythical "lost race". Modern researchers still use Lapham's maps and descriptions to locate or reconstruct sites that once existed. This facsimile edition has a new introduction.
