The Tremper Mound and Works are a
Hopewell (100 BCE to 500 CE) earthen
enclosure and large, irregularly shaped
mound. The site is located in
Scioto County, Ohio, about five miles northwest of
Portsmouth, Ohio, on the second terrace floodplain overlooking the
Scioto River. It was listed on the National Register of Historic Places in 1972.
Site description

The Tremper Works include a large earthen enclosure in the shape of a flattened oval. Measuring by , the oval was entered through an opening in the southwestern part of the enclosure. At the center of the oval is a large, irregularly shaped mound. Believed by some to be an
effigy mound built in the shape of an animal, although there has never been any conclusive proof of this.
The site was surveyed in the 1840s by
Charles Whittlesey for
E. G. Squier and
E. H. Davis, and an engraving was included in their book
Ancient Monuments of the Mississippi Valley. The site was excavated by William C. Mills of the
Ohio Historical Society in 1915. He discovered numerous postmolds at the base of the mound, revealing the outline of a wooden structure long by wide. The pattern showed that there had been a large building with several smaller chambers at its eastern end.
The site is privately owned and was once a working farm.
Pipes

Another significant discovery made at Tremper were more than 500 objects that had been deliberately broken and left in one of the eastern chambers. The objects included 136 smoking pipes made of
catlinite or
pipestone. Ninety were effigy pipes sculpted in the shapes of animals, notably bears, wolves, dogs, beavers, cougars, otters, turtles, cranes, owls, herons, and hawks.
It had been thought that the material used to make the pipes had been quarried from Ohio pipestone outcrops across the Scioto River from Tremper, but new tests have shown that the majority of the pipes were made from Sterling pipestone from northwestern
Illinois. Many of the Tremper pipes are on display at the
