The earliest documented excavation of an effigy mound group by a professional archaeologist occurred in 1883 when Frederic Ward Putnam and local acquaintances excavated portions of four mounds at the Myrick Park site (47Lc10) in La Crosse, Wisconsin. Putnam worked on one effigy (similar to the short-tailed turtle form) and three conical mounds. Theodore H. Lewis visited the site in 1885 and mapped one additional conical mound. We examined documentation and collections housed at the Peabody Museum of Archaeology and Ethnology at Harvard University. Artifacts include a portion of a Madison Cord Impressed jar (a common Effigy Mound offering) and a trailed rim sherd similar to terminal Late Woodland types. Human remains represent a minimum of 23 individuals: 18 adults and 5 subadults. Dental and skeletal evidence indicates a relatively healthy population with low levels of nutritional deficiency, early life stress, and trauma, similar to other regional Late Woodland populations.
