The Yent Mound (8FR5) is a Santa Rosa-Swift Creek culture archaeological site located on Alligator Harbor west of St. Teresa, Florida. It is on the east side of County Road 370, approximately 2.5 miles from the junction of U.S. Route 98. On May 24, 1973, it was added to the U.S. National Register of Historic Places.
Albany Mounds State Historic Site, also known as Albany Mounds Site, is a historic site operated by the Illinois Historic Preservation Agency. It spans over 205 acres of land near the Mississippi river at the northwest edge of the state of Illinois in the United States. In 1974, the site was added to the National Register of Historic Places list. The historical site is under the provision of the Illinois Historic Preservation Agency, a governmental agency founded in 1985 for the maintaining of historical sites within the state. In the 1990s, the site underwent a restoration project that aimed to return its appearance to its original condition.
The Havana Hopewell culture were a Hopewellian people who lived in the Illinois River and Mississippi River valleys in Iowa, Illinois, and Missouri from 200 BCE to 400 CE.
The Ellis Mounds are a complex of Native American mounds near Marysville in Union County, Ohio, United States. These three mounds form an east-west line on a small ridgeline in a farm field. Believed to have been built by Hopewellian peoples, the mounds are important because they may reveal information about daily life in the Hopewell culture. Archaeologists who study the Hopewell have generally concentrated on their largest ceremonial centers: as a result, while the mortuary customs of the Hopewell are well known, other aspects of their culture are little understood. For this reason, a site such as Ellis that bears the potential of yielding information about such aspects is valuable indeed, especially because its date has not yet been established: Ellis may have been built as early as 300 BC and as late as AD 600. Furthermore, the location of the mounds outside of the Hopewellian heartland farther south may demonstrate the spread of Hopewell influence, since excavations in numerous locations have demonstrated the necessity of assembling a complex society with many workers in order to construct the ceremonial mounds for which the Hopewell are well known.
The Coon Hunters Mound is a Native American mound in the central part of the U.S. state of Ohio. Located near the village of Carroll, it sits on the grounds of the Central Ohio Coonhunters Association.
The Ety Habitation Site is an archaeological site in the central part of the U.S. state of Ohio. Located northeast of the village of Carroll in Fairfield County, it encompasses an area of about 4 acres (1.6 ha), which is covered by a group of hillocks. Here have been found large numbers of artifacts of prehistoric man; the nature of the material found suggests that the Habitation Site was a substantial settlement for a long period, most likely from the Hopewellian period, two thousand years ago. Few Hopewellian sites have been discovered that both yielded such valuable information and were so little damaged by the passage of time; as a result, the Ety Habitation Site is a leading archaeological site.
The Rocky Fork Park Site is an archaeological site in the southeastern part of the U.S. state of Ohio. Located in Rocky Fork State Park in eastern Highland County, the site's earthworks have been designated a historic site because of their archaeological importance.
This is a list of the National Register of Historic Places listings in Calhoun County, Illinois.
The Hubele Mounds and Village Site are an archaeological site in the southeastern part of the U.S. state of Illinois. Located near the community of Maunie in White County, the site has received recognition from the federal government because of its archaeological value. Due to the lack of recent excavations, the site's dates of habitation are debated, ranging from 400 BC in some estimates to AD 1000 in others, but all agree on the site's significance to understanding the prehistory of the region.
Dogtooth Bend Mounds and Village Site is an archaeological site located on the western shore of Lake Milligan in Alexander County, Illinois. The site includes two mounds and a village site stretching northwest of the mounds. The village was inhabited by Middle Mississippian peoples from roughly 900-1600 A.D. It likely served as a trade hub and a social center for residents of the surrounding farmland. Formal archaeological investigation of the site was initiated in 1950 by Irvin Peithman of Southern Illinois University.
The Orr-Herl Mound and Village Site is an archaeological site located along the Ohio River in Hardin County, Illinois, United States. The site consists of a mound, which includes a sizable midden, and the remains of a village. The village was inhabited from roughly 900 to 1500 AD by Mississippian peoples. The site was an important source of fluorspar, which Mississippian peoples used for carvings and beads. The village was likely a manufacturing site for fluorspar items, which were then traded to other villages; this theory is supported by fluorspar artifacts recovered from the Kincaid Site, a Mississippian chiefdom center on the Ohio River in Illinois.
The Cleiman Mound and Village Site is a prehistoric archaeological site located near the Mississippi River in Jackson County, Illinois. The site includes an intact burial mound and the remains of a village site. The village was inhabited by a number of prehistoric cultures during the Archaic, Woodland, and Mississippian periods; settlement at the site began prior to 400 B.C. and lasted through 1300 A.D. The mound was built during the Middle Woodland Period by Hopewellian peoples and is likely the only Hopewell mound in the Mississippi Valley in Southern Illinois.
The Wilson Mounds and Village Site is a prehistoric archaeological site located in and around the Marshall Ferry Cemetery in Rising Sun, White County, Illinois. The site includes twelve Hopewell burial mounds and a village site.
The Emerald Mound and Village Site is a pre-Columbian archaeological site located northwest of the junction of Emerald Mound Grange and Midgley Neiss Roads in St. Clair County, Illinois. The site includes five mounds, two of which have been destroyed by modern activity, and the remains of a village. Middle Mississippian peoples inhabited the village, which was a satellite village of Cahokia. The largest of the mounds is a two-tiered structure that stands 50 feet (15 m) high; its square base is 300 feet (91 m) across, while its upper tier is 150 feet (46 m) across. At the time of its discovery, the mound was the second-largest known in Illinois after Monks Mound at Cahokia.
The Horseshoe Lake Mound and Village Site is a pre-Columbian archaeological site located on the northeast shore of Horseshoe Lake in Madison County, Illinois. The site includes a platform temple mound and a village site with the remains of multiple houses. The site was inhabited by Mississippian peoples during the Late Woodland period from roughly 600-1050 A.D. The village at the site was part of the settlement system connected to Cahokia; it was a third line community, a class of community distinguished by a single temple mound, in the system. Of the five known third line communities in the Cahokia system, the Horseshoe Lake Site is the only one which is relatively intact. The site also includes substantial plant and animal remains, which indicate that its settlers produced maize.
Duncan Farm is an archaeological site located on a farmstead south of Illinois Route 100 in Jersey County, Illinois, near the city of Grafton. The site, which dates from the Woodland period, includes two burial mounds and a habitation site. The site was part of the Hopewell exchange system in Illinois and is the closest neighboring village site to the Golden Eagle regional transaction center, a major trade and social hub in the system. Archaeologists have suggested that the site is a local transaction center in the Golden Eagle site's region due to its two large mounds, which are roughly 200 feet (61 m) long and 100 feet (30 m) wide each. In addition, the site is archaeologically significant due to its distinctive stratification, which allows its artifacts to be easily dated.
The John Chapman Village Site is a prehistoric archaeological site located in the Apple River Valley south of Hanover, Illinois. The site includes a village area and a platform mound; the latter is the only known platform mound in the Apple River Valley. The village was occupied from roughly 1100 to 1250 A.D., toward the end of the Late Woodland period and the beginning of the Mississippian period; it is associated with a transitional phase between the two periods known as the Bennett Phase. Archaeologists have hypothesized that the site formed part of a trade network between Cahokia and settlements further north, such as Aztalan, as evidenced by the artifacts found at the site.
The McCune Mound and Village Site is a prehistoric archaeological site located in Whiteside County, Illinois near the city of Sterling. The site consists of a single mound, 3 metres (9.8 ft) high and 23 metres (75 ft) in diameter, and five depressions that may have been housing sites. The site was occupied by Upper Mississippian peoples from roughly 1200 to 1500 A.D.; it is considered part of the Langford tradition, a subset of Upper Mississippian culture found in northwestern Illinois. Modern archaeologists first documented the site in 1961. As a relatively intact site with a single-component habitation, the site was considered to have the potential to provide significant information on the Langford tradition.
