Name/Title
S21.04.002Description
The highest point in Ohio at Campbell Hill in Logan County, Ohio. Campbell Hill is named for Charles D. Campbell of Bellefontaine, who owned this land from 1898 to 1937. A marble stone marker atop the hill, set in 1900 by the U.S. Coast and Geodetic Survey, marks it as the highest point in Ohio at an elevation of 1549.09 feet. Between 1951 to 1969 the federal government operated the site as part of the North American Air Defense Command (NORAD). It was converted to civilian use as a vocational education center in 1974. Campbell Hill sits on an upland known as the Bellfontaine outlier. The Bellefontaine outlier is an elongated body of Devonian rocks surrounded by older Silurian rocks. Nowhere else in Ohio is there an outlier that is so large or so far removed from its main outcrop belt. The bedrock at this locoation is covered by a thick layer of Pleistocene Ice Age glacial sediment. The image was made in 1989.
