Question: Ohio Brush Creek rises in southeastern Highland County, and flows generally southwardly into Adams County, past the 1348 ft -long, three-foot-high prehistoric effigy mound on a plateau of the which crater, along Ohio Brush Creek in Adams County, Ohio?
Context: Brush Creek or Rincon Creek is a tributary of Santa Rosa Creek in Sonoma County, California.  Brush Creek rises in the southern slopes of the Mayacamas Mountains within Sonoma County.  The lower reach of the creek is a suburban medium density residential area in the city of Santa Rosa, and that reach of Brush Creek has been restored during the 1990s under a U.S. Environmental Protection Agency grant to promote steelhead migration and spawning.  Further restoration and incorporation into citywide park planning is currently underway as of 2006.  The location of the confluence with Santa Rosa Creek is particularly noteworthy, since it was a locus of prehistoric life as a village of the Pomo people and a scenic geologic feature of massive flat boulder outcrops within the stream channel.

William Romain received his Ph.D. in archaeology from the University of Leicester and M.A. degree in anthropology from Kent State University.  He is Director of The Ancient Earthworks Project.  He specializes in the study of ancient religions, cognitive archaeology, and archaeoastronomy.  William Romain pioneered the use of LIDAR technology for the analyses of ancient earthworks - most notably those of the Eastern Woodlands.  In 2011 Romain led a team of archaeologists (collectively known as The Serpent Mound Project) in an investigation of Serpent Mound, in Adams County, Ohio.  This was the first major investigation of the effigy in more than one hundred years and included Geoprobe coring, hand coring, limited excavation, ground-penetrating radar, and electric resistivity analysis.  Among the results were new radiocarbon dates for the effigy suggesting it was built about 2,300 years ago by people of the Early Woodland period.  Romain is a past advisor to the Board of Trustees for the Heartland Earthworks Conservancy, former research associate with the Newark Earthworks Center at Ohio State University and past recipient of the Archaeological Society of Ohio's Robert Converse award for Outstanding Contributions to Ohio Archaeology.
