Hovey Lake-Klein Archeological Site (12 PO 10) is an archaeological site of the Caborn-Welborn variant of the Mississippian culture. Hovey Lake-Klein Archeological Site is located on the west bank of Hovey Lake, a backwater lake near the Ohio River close to its confluence with the Wabash River. The site was an extensive village occupation dating between 1400-1650 CE.
The site is located on a terrace 3.6 km from the Ohio River adjacent to Hovey Lake, in Indiana. The site is roughly 11.8 ha. There was a centrally located plaza as well as an encircling palisade with bastions. Houses were typical Mississippian rectangular wall trench wattle and daub structures set in shallow basins. Many had prepared clay hearths. Located near most houses were special pits used to store maize and other dried foods. The pits were large enough to have stored enough grain to feed 7 to 12 people for a year.
