Anyone know the location of two Indian mounds located inside of ARMCO Park in Warren County? According to the Ohio Historic Inventory there are two located there - ARMCO Park Mound I and ARMCO Park Mound II. It also has listed the Mann Mound in Jacksonburg - would that be the name of the one on Rt.122 going into Preble County? Take care, J. Larry Helton, Jr.
