Shrum Mound

Shrum Mound stands on a high bluff on the west side of the Scioto River. It measures approximately 20 feet (6 m) in height and about 100 feet (30 m) in diameter.

The mound is bordered by an active quarry lake known locally as the McKinley Avenue Quarry, operated by the Columbus Division of Water. Limestone was extracted there from the late 19th century into the early 20th century, after which the exhausted quarry filled with water. Beginning in the 1970s the city used the flooded quarry as a repository for residual byproducts of municipal water treatment. As of 2026 the city has undertaken a large dredging project there, citing the site's limited remaining capacity.

Access to the summit has changed over time. The photograph archive of the Ohio History Connection, spanning 1929 to 1963, describes a set of formal steps leading to the top. More recent visitor accounts instead describe two unpaved dirt paths to the summit, a gentler route from the park's entry gate and a steeper, more direct route on the western side.

The mound has never been archaeologically excavated, and its precise contents remain unknown. An archaeologist of the Ohio History Connection, Neil Thompson, has stated that the mound likely still contains numerous interments.
