Culberson Woods State Nature Preserve

Cowan Lake, also known as Cowan Creek Reservoir, is a lake within Cowan Lake State Park in Clinton County, Ohio, United States. Its surface area is 692 acres (2.80 km2). Cowan Lake lies near the Cincinnati Arch, an uplifting of bedrock that occurred during the Appalachian Mountains' building process. The erosion of this arch in the Cowan region exposes fossil-rich limestone. The limestone near Cowan and other parts of the exposed arch are some of the most famous fossil hunting fields in the world. The lake takes its name from Cowan Creek, the creek that was dammed in 1950 to form the lake. Its source is at 39°24′12″N 83°41′18″W. Cowan Creek was named for John Cowan, the first surveyor of the area. Cowan Lake State Park, which includes the lakes and its immediate surroundings, was dedicated in 1968.

Pansy Methodist Church is a historic church at Pansy in Clinton County, Ohio, United States. Built in 1885, it was formerly home to a congregation of the Methodist Episcopal Church. Few changes have been made to the church or to its adjacent church school since they were built: neither building has any central heating or plumbing, and the interiors retain the open, undivided floor plans with which they were designed. Built in 1885 and 1900 respectively, the church and school are a mix of architectural styles. Measuring approximately 28 by 46 feet (8.5 by 14.0 m), the church is a Gothic Revival building with three ogive windows on each side; worshippers entered through a large front door in a Gothic arched doorway with a transom light. A small tower with a belfry sits atop the roof at the front of the church; it is decorated with ornate latticework. Nearby, the school measures 29 by 40 feet (8.8 by 12.2 m); its Romanesque Revival style is evidenced by elements such as pilasters on the corners and decorative brickwork below the roofline. Both buildings are constructed of brick on stone foundations and feature slate roofs.In 1973, the church and school were designated a historic district and listed on the National Register of Historic Places, due to their historically significant architecture. Key to this designation was their place as a rare example of the nineteenth-century country church; they were seen as evoking a sense of historic rural Christianity in the region.

The Cowan Creek Circular Enclosure (33CN11) is an earthworks complex in the southwestern part of the U.S. state of Ohio. Named for its location near the stream known as Cowan Creek, the enclosure is an important archaeological site, and it is protected as part of a state park. The Cowan Creek Circular Enclosure is not easily visible to the average observer on the ground. A survey conducted in 1949 observed that the enclosure was approximately 90 feet (27 m) wide, but even at that time, it had virtually no height; the only practical method of observing the site's extent was via aerial photography. Most of what is known of the site is derived from a related site not far away from the enclosure. The latter site, known as the "Cowan Creek Mound", was excavated in 1949; archaeological work revealed that the mound had been constructed circa AD 500, near the end of the period during which the Adena culture inhabited the region. This mound was part of a substantially larger group: more than twenty burial mounds were located along Cowan Creek near the enclosure, but little is known about most of them: by the time that Raymond Baby was leading the Cowan Creek Mound excavation, a dam on the creek had been completed, and the water levels of a reservoir covered the mounds before most could be investigated. The entire group remains beneath the surface of Cowan Lake to the present day, except for the enclosure. Today, the Circular Enclosure lies near the shore of Cowan Lake; the underwater site of the Cowan Creek Mound is only about 300 feet (90 m) away, and the enclosure lies in the middle of a peninsula in the lake. The site is now located within Cowan Lake State Park, slightly less than 1 mile (1.6 km) south of the present State Route 730. Officials have sought to allow the site and surrounding lands to return to the condition in which they existed before the region was settled. As a result, the site has never been subjected to intensive professional testing; archaeologists accordingly are unaware of whether any additional sites, such as a village location, might be nearby. In 1974, the Cowan Creek Circular Enclosure was listed on the National Register of Historic Places because of its value as an archaeological site. Four other Clinton County archaeological sites are listed on the Register: the Beam Farm Woodland Archaeological District, and the Hillside Haven, Hurley, and Keiter Mounds.
