Colerain Earthworks

Colerain Earthworks is located on the Great Miami River at the confluence of Banklick Creek. 

[From the Surveys and Notes of JAMES MCBRIDE.]

"This work is one of the first magnitude; and in many respects bears a close resemblance to the great work on the North fork of Paint creek. (See Plate IX.) It is situated near the village of Coleraine, Hamilton county, Ohio, on the right bank of the Great Miami river, and encloses an area of ninety-five acres. The walls have an average height of nine feet, and have an exterior ditch of proportionate dimensions. The terrace upon which the work is located is thirty feet above the usual stage of water in the river.p036

The outwork, of which A is an enlarged plan, possesses all the features of a bastion, and was perhaps designed as such. It could hardly have been intended as a gateway; for, although the ditch is interrupted for a narrow space at c, the embankment is unbroken.

The transverse section of the wall, a b, demonstrates the artificial origin of the work, which it is not probable any one would be disposed to deny. The upheaved gravel upon the exterior side of the wall, wherever it is under cultivation, supports dwarfed and sickly maize; while on the inner side, the grain is luxuriant. This feature and its cause are indicated in the section."
