Connected to a 20-acre Observatory Circle, this geometric earthwork demonstrates sophisticated astronomical knowledge. The walls and gateways encode all eight lunar standstill rise and set points \\cite{mickelson_lepper_2007}. The Octagon's eight walls (each approximately 550 feet long) and Observatory Circle form one of only two known circle-octagon pairs in the Hopewell world, the other being High Bank Works \\cite{hively_horn_1984}. First comprehensively surveyed by Squier and Davis in the 1840s \\cite{squier_davis_1848}. Inscribed as a UNESCO World Heritage Site in September 2023 \\cite{unesco_2023}.",

Located in Heath, Ohio, this is one of the largest circular earthworks in the Americas. Eagle Mound at the center covers the remains of a large ceremonial structure \\cite{ohc_newark}. The walls vary from 4 to 14 feet in height at the monumental gateway. Unlike the Octagon, no solar alignments have been confirmed at the Great Circle \\cite{hively_horn_1982}.

This confirmed earthwork consists of parallel walls approximately 60 meters (200 feet) apart, aligned on an azimuth of approximately 212° toward Chillicothe \\cite{schwarz_2016}. First documented by James and Charles Salisbury in 1862, who followed the walls for 6 miles through 'tangled swamps and over hills, still keeping their undeviating course' \\cite{salisbury_salisbury_1862}. LiDAR analysis suggests the road was sunken between the walls \\cite{romain_burks_2008}. Test excavations in 2009 revealed a thin layer of white limestone that may have paved the road \\cite{lepper_2024}. Still visible above ground in woodland areas too swampy to farm.",

Each mound covered a charnel house where the dead were cremated. Excavations by Squier and Davis in the 1840s, and later Ohio Historical Society work (1920-1922), revealed spectacular artifacts including effigy smoking pipes, mica sheets, copper figures, and obsidian from Yellowstone \\cite{lynott_2015}.

Located on a terrace east of the Scioto River, across from Mound City \\cite{lynott_2015}.
