The Miamisburg Mound is the largest conical burial mound in the state of Ohio and possibly in the eastern U. S.

Archaeological investigations of the surrounding area suggest that it was constructed by the prehistoric Adena Indians (800 BC - AD 100). Built on a 100-foot-high bluff, the mound measures 877 feet in circumference. It was originally more than 70 feet high and has been topped off by a fenced in, paved viewing platform.

Visitors may climb the 116 steps from its base to the summit for a view of the surrounding park. The 37-acre park has picnic tables and a playground.

Ancient historic effigy mound is a Native American earthwork, possibly created by the Hopewell Indians.
The “Alligator” Mound is one of the two effigy mounds in Ohio.
Nearby are the Newark Earthworks which were built by the Hopewell culture between 100 B.C. and A.D. 400. Archaeologists are uncertain who built Alligator Mound but estimate that it is of Hopewell construction.   

A Cryptozological EarthCache

Carlisle Fort, or Big Twin Works, is a hilltop fortification which lies on the west bank of Big Twin Creek, about 2 1/2 miles south of Germantown and about one mile west of Carlisle. The creek empties into the Great Miami River about four miles to the south.

     C.E. Blosser suggested the name of the fort in regards to its location near Carlisle. Hilltop fortifications were thought to be of a later time than the mounds and hilltop enclosures. The ancients, to whom these works are attributed to, are the Hopewell Indians who lived within the bounds of Ohio nearly 2000 years ago.

     Carlisle Fort was thought to have been built from AD 1 to AD 300. Historians thought this type of defensive fortification was a reflective measure concerning a declining cultural race. The first survey of the site was by S.H. Binkley and C.E. Blossom in 1835. They returned to the site in 1875 for further examination.

Carlisle Fort

The Octagon Earthworks are the largest set of geometric earthen enclosures ever built. They are part of the Newark Earthworks complex of prehistoric Indian earthworks. 

The Newark earthworks (including the Octagon Earthworks) were constructed by the people of the so-called "Hopewell" culture, which was the human presence in this valley during the years 200BC to 500AD.  


Geometric Mounds

Serpent Mound is the largest and finest serpent effigy in the United States. Nearly a quarter of a mile long, Serpent Mound apparently represents an uncoiling serpent 

In 1991, wood charcoal was found during an excavation of the Serpent Mound that indicated a radiocarbon dating of the Fort Ancient culture era, long after the Adena culture ceased to exist. This dating indicated that the Serpent Mound could have been constructed between A.D. 1000-1550.
