Context paragraphs:
Cranberry Creek Archeological District: Cranberry Creek Archeological District, also known as Cranberry Creek Mound Group, is an ancient American Indian burial mound site from circa AD 100–800 near New Miner, Wisconsin, United States.  It is three miles east of Necedah National Wildlife Refuge in Juneau County.  It is part of the "effigy mound culture" of native peoples in Wisconsin, who practiced the "respectful burial of their dead".

Effigy mound: An effigy mound is a raised pile of earth built in the shape of a stylized animal, symbol, human, or other figure and generally containing one or more human burials.  Effigy mounds were primarily built during the Late Woodland Period (350-1300 CE (current era)).  Conical and linear mounds, the predecessors of effigy mounds may date from as far back as 700 BCE (before the current era).  They remain places First Peoples frequent to visit and speak with ancestors, to put down tobacco and to give thanks.  These sites are primarily visited by Hochungra (pl.  of Hochunk) people whose ancestors likely built the great majority of them, though they are also visited by people from other original indigenous nations such as Anishinaabe (Ojibwe), Kikapu, Oneida, Menominii who reside in Wisconsin and surrounding areas.  There also remains the possibility that a greater diversity of First Peoples such as ancestors of those named nations may have contributed to building some percentage of the mounds.  That is to say that ancestral Hochunk likely popularized the form and other groups may have adopted the practice of building effigy mounds from having observed the Hochunk ancestors methods and aesthetics surrounding their construction.

Turkey River Mounds State Preserve: Turkey River Mounds State Preserve is a historic site located near the unincorporated community of Millville, Iowa, United States.  The 62 acre preserve contains thirty-eight of forty-three Native American mounds located on a narrow Paleozoic Plateau at the confluence of the Mississippi and Turkey rivers.  They vary in size and shape and are 1.3 ft to 6 ft in height.  The conical mounds range from 20 ft to over 100 ft in diameter.  The linear mounds vary from 80 ft to 175 ft in length.  There is one effigy mound in the shape of a panther that is 98 ft long and 40 ft wide.  There are also compound mounds in the preserve.  The mounds were constructed during the Woodland period (500 BCE and 900 CE).  They were used for burials and ceremonial places, and are now protected by law.  The preserve is also home to a variety of trees, prairie grasses and flowers.

Intaglio (burial mound): Intaglio (from Italian: "intaglio" ] ) is a term from art applied to burial mounds that refers to a design cut into a hard surface.  In this case, the burial mounds have designs cut into the ground, though "intaglio" broadly applies to burial mounds which are raised above the natural surface of the terrain.  There are much more rare forms where they are left as indents below the natural terrain.  These are typically in some effigy shape such as the Panther Intaglio Effigy Mound, which can be seen in Fort Atkinson, Wisconsin, where it is the last remaining intaglio mound in the state.

Serpent Mound: The Great Serpent Mound is a 1348 ft -long, three-foot-high prehistoric effigy mound on a plateau of the Serpent Mound crater along Ohio Brush Creek in Adams County, Ohio.  Maintained within a park by the Ohio History Connection, it has been designated a National Historic Landmark by the United States Department of Interior.  The Serpent Mound of Ohio was first reported from surveys by Ephraim Squire and Edwin Davis in their historic volume "Ancient Monuments of the Mississippi Valley", published in 1848 by the newly founded Smithsonian Museum.

McCollum Mound: McCollum Mound, also known as Turkey Creek Mound and village, is a historic mound and village site located near Chester, Chester County, South Carolina.  The site is one of less than two dozen mounds of aboriginal origin in the state of South Carolina.  The mound was built in three, or possibly more, stages.  The Turkey Creek mound and village were probably inhabited during the late prehistoric and early historic periods.  The mound is located on the Broad River approximately 500–600 feet downstream from the McCollum Fish Weir.

William F Romain: William Francis Romain (born 1948) is an American archaeologist, archaeoastronomer, and author.  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.

Lizard Mound County Park: Lizard Mound County Park is a county-operated park in Washington County, Wisconsin near the city of West Bend.  Established in 1950, it was acquired by Washington County from the state of Wisconsin in 1986.  It contains a significant well-preserved effigy mound group.

Alligator Effigy Mound: The Alligator Effigy Mound is an effigy mound in Granville, Ohio, United States.  The mound is believed to have been built between AD 800 and 1200 by people of the Fort Ancient culture.  The mound was likely a ceremonial site, as it was not used for burials.

Man Mound: The Man Mound is a prehistoric humanoid earthwork located in Greenfield, Sauk County, Wisconsin, east of the city of Baraboo.  Constructed during the Late Woodland period, the mound is the only surviving anthropomorphic effigy mound in North America.  The mound depicts a horned humanoid figure and may have held religious or ceremonial significance to its builders.  The mound was preserved as a county park in 1908, listed on the National Register of Historic Places in 1978 and designated a National Historic Landmark in 2016.
