Summary
 

The Mt. Horeb Earthwork is an Adena earthen enclosure located just outside Lexington, Kentucky, along Elkhorn Creek.  It was constructed over 2,000 years ago and consists of a circular ditch and embankment.  An an earthen causeway is located on its west side. Archaeologists believe that the Adena people used Mt. Horeb as a location for periodic social gatherings.  Today the Mt. Horeb Earthwork has been reconstructed, and it is a protected recreational area owned by the University of Kentucky named Adena Park.

Research Focus

Archaeological investigations began at Mt. Horeb in 1939 under the direction of William S. Webb of the University of Kentucky.  Many local men participated in archaeological excavations around the Bluegrass in order to get back to work during the difficult years of the Great Depression.  In order to understand how the earthwork and enclosure were built, the crew dug horizontal and vertical trenches through the ditch and embankment.

Findings & conclusions

Measuring over 295 feet (90 meters) across, the Mt. Horeb Earthwork consists of an outer earthen embankment, a ditch to its interior, a circular pattern of large posts to the interior of the ditch, and finally, a flat interior. A causeway extends to the west of the earthwork. 

Very few artifacts were recovered from the center of the enclosure.  This suggests that at the conclusion of rituals conducted at this site, those who participated made an effort to clean the area.  

Mt. Horeb appears to represent a place where Adena people gathered to carry out important rituals over several decades.

What's Cool?

During the excavation of Mt. Horeb, archaeologists uncovered the remains of a structure that was built and used prior to the construction of the ditched embankment (earthwork).  The structure consisted of a circle of posts  grouped into pairs.  The average diameter of the posts was just under a foot.  There is no evidence that the builders wove smaller saplings between the posts to create a solid wall.  Thus, the structure may have looked more like a circular standing screen than a walled structure.

Archaeologists think that the paired-post structures were open-air meeting spaces where Adena groups held important ceremonies.  The enclosure’s posts would have set up a boundary around this ritual space and limited access to only those directly involved in the ceremonies. However, since the earthwork sat on a prominent place on the landscape people excluded from the ceremonies would still know an important riutal was underway. Imagine under the cover of night looking up at the earthwork and seeing the flicker of fire and billows of smoking arising from behind the enclosure.

With the construction of the ditched enclosure, there was no longer a need for the paired-post structure.  The outer walls of the embankment, however, would have served a similar purpose thereby effectively screening outsiders from events taking place within the enclosure.
