The Wesley Butler Archeological District (designated 33HA249) 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.In the late 1950s, an archaeological field survey visited the site repeatedly. Comparatively few artifacts were found: only scrapers, an axe, and tiny projectile points were found, all in tiny numbers, although numerous pieces of chert were discovered with evidence that humans had worked them. The survey found absolutely no pottery whatsoever, confusing the surveyors and leading them to suggest that the mounds and the village site had been the result of separate occupations of the same location.The western portion of Hamilton County contains many archaeological sites, due primarily to its favorable terrain. The area is well watered by the Ohio and Miami Rivers; consequently, prior to white settlement of the region, there were large amounts of game, and edible plants could be found in large numbers. For this reason, the Wesley Butler site has been inhabited for at least six thousand years. In recognition of the district's archaeological value, it was listed on the National Register of Historic Places in 1976.

The Rennert Mound Archeological District is a group of archaeological sites in the southwestern part of the U.S. state of Ohio. Located west of Elizabethtown in Hamilton County, the site is composed of one Native American mound and the remnants of two others, spread out over an area of 40 acres (16 ha).The central part of the district is the Rennert Mound (also known as the "Minnie Rennert Mound"), which retains its original shape despite digging by locals in the past. Because the mound has never been excavated professionally, no significant artifacts have been recovered from it; consequently, the culture of the builders is unknown. The surrounding field has yielded plentiful lithic cores of white and tan chert, but too few cores have been found to justify classification of the fields as a village site.: 120  Due to its location and shape, the mound is believed to have been built by Adenan or Hopewellian peoples, both of which typically buried many bodies and large numbers of grave goods within mounds of this size. Another mound was once located approximately 90 feet (27 m) to the west, but it has been destroyed. The preservation of the one mound despite the destruction of the other is likely due to recent intervention: in the early twentieth century, landowner John Rennert planted trees all around this mound to preserve it, but he made no such efforts around the other mounds.: 120 Three mounds once composed the Rennert complex, but neither of the others can be distinguished from the surrounding landscape; however, it is believed that an archaeological investigation might be able to discover their locations. Consequently, like the Rennert Mound, the bases of these two mounds are potential archaeological sites. Yet other sites have been found in the vicinity: a somewhat smaller mound tops a hill to the north,: 120  and the Wesley Butler Archeological District, composed of multiple mounds and a village site, lies just to the southwest.: 121  In 1975, the Rennert Mound and the sites of the two destroyed mounds were listed on the National Register of Historic Places for their archaeological significance.

The State Line Archeological District (also known as the State Line site) is a complex of archaeological sites and national historic district located west of Elizabethtown, Ohio, United States. Located on both sides of the Indiana/Ohio border, the historic district is composed of five contributing properties spread out across 8 acres (3.2 ha) of land. It is believed to have been the site of a village of the Fort Ancient culture of prehistoric Native Americans. Radiocarbon dating has revealed that State Line was occupied at approximately the same time as the SunWatch site near Dayton, Ohio and the Turpin site at Newtown, Ohio, while post-excavation analysis has shown that the inhabitants of the three sites were all members of the same culture.: 113–114  Occupation of these sites is believed to date from the Middle Fort Ancient period of the thirteenth century AD.: 91 A leading part of the district is a village site, also known as the "Henry Bechtel Village"; it includes a wide midden and a cemetery. Plowing of the fields at the village site has frequently turned up a wide range of artifacts, including burial pits, hearths, and trash pits. Ceramics found during excavation at the site have typically been tempered with shells. This pottery shares many characteristics with that produced by Middle Mississippian cultures, such as distinctive styles of painting and the presence of pottery modelled after owls and the heads of humans.Because the midden is wide but quite shallow, it has been proposed that the village's population was significant but its period of occupation was short.Among the district's contributing properties are three small burial mounds, which appear to be the work of earlier mound building peoples. At one time, the site comprised five mounds, but only three remain within the district's boundaries.In 1975, State Line was listed on the National Register of Historic Places for its archaeological significance.

The Mount Nebo Archaeological District is a historic district in the southwestern corner of the U.S. state of Ohio. Located near North Bend, the district lies near the intersection of Mount Nebo and Brower Roads. Included in the district's 40 acres (16 ha) of area are two contributing properties: one large archaeological site and one Native American mound.The southwestern corner of Hamilton County contains many archaeological sites, including nearly fifty in the nearby Shawnee Lookout Archeological District. This part of the state was heavily frequented in the pre-Columbian era because its countryside was highly favorable for human habitation: the Ohio and Miami Rivers provide good transportation; the land is fertile; and abundant food can be found.Mount Nebo has gained a reputation as one of the most valuable archaeological sites in southwestern Ohio. Local amateur archaeologists have frequented the area, as large numbers of artifacts can be found on the surface of the ground. Among the findings are artifacts both of the Archaic and Woodland periods, thousands of years apart from each other. In recognition of its archaeological value, the Mount Nebo Archaeological District was listed on the National Register of Historic Places in 1975, approximately three months after the district on Shawnee Lookout.

The Shawnee Lookout Archeological District is a historic district in the southwestern corner of the U.S. state of Ohio. Located southwest of Cleves in Hamilton County's Miami Township, the district is composed of forty-six archaeological sites spread out over an area of 2,000 acres (810 ha). Thirty-four of these sites are located in the 1,000-acre (400 ha) Shawnee Lookout Park, which has been called one of the most beautiful parks in southwestern Ohio.The combination of river bottoms and wooded hillsides in Shawnee Lookout made it a highly attractive site for prehistoric settlement. As a result, the lands included in the district have a long record of aboriginal residency: artifacts found in the district's sites span a range of ten thousand years. These artifacts represent many cultures, including various Archaic peoples, the Hopewell tradition, and other Woodland period peoples. Among the artifacts found at one of the sites are a wide range of biological remains, such as bird bones, fish bones, walnuts, turtle shells, and deer bones. In recognition of the archaeological value of the sites composing the district, Shawnee Lookout was listed on the National Register of Historic Places in 1974.
