Backusburg Mounds is located in Kentucky

The Backusburg Mounds (15-CW-65) are an archaeological site in the Jackson Purchase region of the U.S. state of Kentucky. Located near the tiny community of Backusburg in northwestern Calloway County, the mounds are one of the region's premier archaeological sites. Since at least the early years of the twentieth century, the mounds have been well known locally, due partially to their large size; the largest mound measures 150 by 75 feet (46 m × 23 m) at the base. Located on a ridgeline above a fork of the Clarks River, the mound bears a peculiar shape; its size and shape have caused observers to suggest that it might actually be the remnants of a series of smaller mounds placed next to each other. As late as the 1930s, this largest mound had never been plowed; it lay in dense woodland, and among the trees growing upon it were some of considerable size. Nevertheless, the mound has not been preserved entirely without damage; various parts of the mound have been dug into at various times and have yielded numerous artifacts. Such findings occurs in the area; a field close to Backusburg has long produced skeletons, projectile points, and pottery when plowed, leading to its identification as a former village site.^[2]
