A volume of Hamilton County history, published in the nineteenth century, described the Benham Mound, named for a local farmer, as "a fine, large mound," which measured 8 feet (2.4 m) high and with a circumference of approximately 200 feet (61 m). Other dimensions exist that suggest a smaller structure that stood approximately 6.8 feet (2.1 m) in height and 57 feet (17 m) in diameter east and west and 50 feet (15 m) north to south. The location of the mound is on a hilltop that overlooks the valley of a tributary creek that flows west into the Mill Creek, which correlates with Section 30 of the original Columbia Township, near the Montgomery turnpike (now U.S. Route 22), that is, near end of present-day Grand Vista Avenue. The Norwood Mound lies approximately 1.5 miles (2.4 km) to the southwest.
During the late nineteenth century, local residents partially excavated the mound and the ground around it; their diggings revealed significant amounts of mica and divers types of stone tools, including axes, scrapers, chisels, and flint projectile points. These findings, combined with the location of the mound itself, have led archaeologists to conclude that Benham Mound was built by people of the Hopewell tradition. Because of its archaeological value, the Benham Mound was listed on the National Register of Historic Places in 1974.
