“…If people were moving large amounts of dirt around at that time, it is not inconceivable that contemporaries to their east were moving around large amounts of rocks. An interesting comparison is between the Serpent Mound in Ohio, which recently has been redated to 2300 years ago (Monaghan and Herrmann, 2019; Romain et al., 2017; cf. Lepper et al., 2019), and the serpentine Row Platform at Oley Hills.…”
More than 5000 rock structure sites are found in northeastern United States, but their cultural attribution has long been debated. Some argue than many are prehistoric in origin, while others maintain they all date to colonial times. Few have been dated, and of those that have, the association of the dated material and the rocks can be challenged. Here, we provide luminescence analysis on the rocks themselves at a large site in eastern Pennsylvania. Our results suggest an age coeval with the Adena culture of the Ohio Valley.

“…Serpent Mound is the preeminent effigy mound in North America yet the age of its original construction is the subject of on-going debate (Herrmann et al, 2014;Lepper, 2018Lepper, , 2020aLepper, , 2020bLepper et al, 2018Lepper et al, , 2019Monaghan and Herrmann, 2019;Romain, 2019;Romain et al, 2017;Romain and Herrmann, 2018). Attempts to obtain chronometric dates for the mound have, so far, yielded only terminus post quem dates, because none of the dated samples can be reliably linked to its original construction.…”

The effigy mounds of the Upper Midwest and the Ohio Valley long have been regarded as distinct and independent cultural developments. A review of effigy mound iconography in both regions reveals similarities suggesting that they are elements of a shared cultural tradition. Comparisons with rock art imagery from the Upper Midwest and Missouri, the inferred centers of this artistic and ceremonial florescence, reveal co-occurrences of specific motifs and provide additional evidence of cultural connections among the Late Woodland to early Late Precontact societies inhabiting the lower Missouri, Mississippi, and Ohio river valleys. Oral traditions of Native American groups with documented connections to these regions allow this rich corpus of imagery to be understood as key episodes in their genesis stories.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
