Fort Ancient is a Native American earthworks complex located in Washington Township, Warren County, Ohio, along the eastern shore of the Little Miami River about seven miles (11 km) southeast of Lebanon on State Route 350. The site is the largest prehistoric hilltop enclosure in the United States with three and one-half miles (18,000 ft) of walls in a 100-acre (0.40 km2) complex. Built by the Hopewell culture, who lived in the area from the 200 BC to AD 400, the site is situated on a wooded bluff 270 feet (82 m) above the Little Miami. It is the namesake of a culture known as Fort Ancient who lived near the complex long after it was constructed.
The Benham Mound is a Native American mound in the southwestern part of the U.S. state of Ohio. Located in modern Amberley Village in Hamilton County, the mound is an archaeological site.
The Burchenal Mound is a Native American mound in the southwestern part of the U.S. state of Ohio.
The Wesley Butler Archeological District is a historic district composed of a group of archaeological sites in the southwestern corner of the U.S. state of Ohio. Located south of Elizabethtown, the district comprises three Native American mounds and the site of a Native American village, spread out over an area of 40 acres (16 ha). Although the mounds are built atop part of the village site, they are not contemporaneous: the mounds were built by Woodland peoples, but the village dates from the far older Archaic period.
The Mathew Mound is a Native American mound in the southwestern part of the U.S. state of Ohio. Located off Oak Road near the village of Evendale, the mound is believed to have been built by members of the Adena or Hopewell peoples during the Woodland period.
The Perin Village Site is an archaeological site in the southwestern part of the U.S. state of Ohio. Located in Newtown in Hamilton County, it is believed to have been inhabited by peoples of the Hopewell tradition.
The Demoret Mound is a Native American mound in the southwestern part of the U.S. state of Ohio. Located west of Ross in Butler County, the mound appears to have been constructed by Native Americans of the Woodland period. Although the Demoret Mound has not been excavated, it is likely to contain evidence of funerary practices; excavation of similar mounds has revealed postholes of structures believed to be houses or ceremonial buildings. Consequently, the archaeological value of the mound is significant; excavation might reveal information about practices not found in other mounds. In recognition of its archaeological value, the Demoret Mound was added to the National Register of Historic Places in 1975.
The Great Mound is a massive Native American mound in the southwestern part of the U.S. state of Ohio. Located in Section 19 of Madison Township in Butler County, it has a height of 43 feet (13 m) and a circumference of 511 feet (156 m). Its total volume is nearly 825,000 cubic feet (23,400 m3), making it the largest mound in Butler County and one of the largest in southwestern Ohio. Because of the mound's height and its placement on a ridgeline, an individual at the summit can see for a great distance. In the late nineteenth century, it was theorized that mounds such as the Great Mound were built as observation or watch points, and that the builders maintained the ability to light fires atop the mounds as a method of communicating across wide distances. The potential of these mounds for long-distance communication was demonstrated in 1990 by three groups of volunteers. After climbing the Great Mound, the first group established visual contact with the Hill-Kinder Mound in Franklin, from which point the observers of the second group contacted the third group atop the Miamisburg Mound near Dayton.
The Mann Mound is a Native American mound in the southwestern part of the U.S. state of Ohio. Located near the unincorporated community of Jacksonburg in Butler County, it is tree-covered and sits on the edge of a field in Section 12 of Wayne Township. Its height is approximately 20 feet (6.1 m), and its circumference is approximately 540 feet (160 m).
The Roberts Mound is a Native American mound in the southwestern part of the U.S. state of Ohio, USA. Located northwest of Auburn in Butler County, the mound sits in Section 36 of Reily Township; it is the only mound in the far southeastern part of the township.
The D.S. Rose Mound was a Native American mound in the southwestern part of the U.S. state of Ohio. Located north of Huntsville in Butler County, the mound was also known as the "Holloway Mound." Its placement on a ridgeline above flat countryside has been interpreted as an indication that it was built by the Adena culture.
The Portsmouth Earthworks are a large prehistoric mound complex constructed by the Ohio Hopewell culture mound builder indigenous peoples of eastern North America. The site was one of the largest earthwork ceremonial centers constructed by the Hopewell and is located at the confluence of the Scioto and Ohio Rivers, in present-day Ohio.
The Dunns Pond Mound is a historic Native American mound in northeastern Logan County, Ohio, United States. Located near Huntsville, it lies along the southeastern corner of Indian Lake in Washington Township. In 1974, the mound was listed on the National Register of Historic Places as a potential archeological site, with much of its significance deriving from its use as a burial site for as much as nine centuries.
The Lake Ridge Island Mounds are a group of small hills in Logan County, Ohio, United States that have been thought to be Native American mounds. Located in an area of about 5 acres (2.0 ha) at the northern end on Lake Ridge Island in Indian Lake, the mounds are near the village of Russells Point in the southeastern corner of Stokes Township. State Route 368 passes a short distance to the east of the mounds, even weaving at one point to avoid them. The four mounds on the island are small, not reaching a height greater than 3 feet (0.91 m) or a diameter greater than 40 feet (12 m); they are small enough that they appear to be natural knolls. A report produced in the 1970s observed that the mounds were in "excellent" condition at the time, never having been disturbed by artifact seekers.
The Mann Site is a Crab Orchard culture site located off Indian Mound Road in Mount Vernon, Posey County, Indiana. It was placed on the National Historic Register on October 1, 1974. Exotic ceramics and other artifacts found at the site reflect contact with Ohio Hopewell people, in addition to more distant peoples in the Southeast of the Swift Creek culture of the Georgia Piedmont and Gulf Coastal Plain.
The Keiter Mound is a Native American mound in the southwestern part of the U.S. state of Ohio. Located north of the city of Wilmington, it sits on a wooded hill above the stream bottom of a small secondary creek, the Anderson Fork. About 5.5 feet (1.7 m) tall at its highest point, the mound measures 58 feet (18 m) from north to south and 65 feet (20 m) from east to west.
The Beam Farm Woodland Archaeological District is a group of archaeological sites in the southwestern part of the U.S. state of Ohio. Located at 3983 Stone Road near the village of Sabina in Clinton County, the district is composed of one Native American mound and two other archaeological sites spread out over an area of 2 acres (0.81 ha). Known as the Beam Farm Mound and the Beam Sites 9 and 12, the sites that compose the district have yielded artifacts from the Adena culture and the Hopewell tradition, both of which inhabited southwestern Ohio during the Woodland period. Because both the Adena and the Hopewell lived around the mound, and because both cultures built mounds, the identity of the people who constructed the Beam Farm Mound cannot be established; all that can be known with reasonable certainty is that it was raised during the early or middle portion of the Woodland period, or between 800 BC and AD 500.
Indian Mound Reserve is a public country park near the village of Cedarville, Ohio, United States. Named for two different earthworks within its bounds — the Williamson Mound and the Pollock Works — the park straddles Massies Creek as it flows through a small canyon.
