100 BCE-400 CE

Formation of the Earthworks

The Earthworks were built likely in the Middle woodland period sometime between 100 BCE and 400 CE.

100 BCE-400 CE


Cincinnati was founded

Cincinnati was founded December 1788 and the Earthworks began to be explored as a curiosity leading to reduction in size and destruction.


Cincinnati Mound truncation

General Wayne had his army cut off the summit of the Mound closest to Fort Washington and the town in order to erect a sentry-box on top of it.  After the top was removed the mound was 35' tall. This mound can be seen in the 1800 painting of Cincinnati as the large mound to the left of the town. The Cincinnati Tablet (Squier and Davis P275 see below) was found in one of these mounds.
