to Kentucky in several places. It was surveyed and mapped by E. G. Squier in 1847 for inclusion in the seminal archaeological and anthrolopological work Ancient Monuments of the Mississippi Valley.[3] Portsmouth Earthworks, Group B[edit]

Overview of the Horseshoe Mound

The northernmost section was made up of a number of circular enclosures, two large horseshoe-shaped enclosures, and three sets of parallel-walled roads leading away in different directions. One set of walled roads extends across the Ohio River

into South Portsmouth, Kentucky to the southwest to Portsmouth Earthworks, Group A. Another set of walled roads lead to the southeast where it also crossed the Ohio River

and lead to Portsmouth Earthworks, Group C.[3] The third set of walled roads lead to the northwest for an undetermined distance, and may point to Tremper Mound
and Works, some 5 miles away. The City of Portsmouth maintains a public park which includes one of the remaining horseshoe-shaped enclosures, known as Mound
Park, it is the only publicly accessible part of the complex.[2] Under the name Horseshoe Mound
