Serpentine Stone Enclosure at Spruce Hill in Ross County, Ohio

Serpentine Stone Enclosure at Spruce Hill in Ross County, Ohio

Serpentine stone work is located on the lowland at the bottom of the hill where Spruce Hill is located. Numerous henge type earthworks are located around Chillicothe that were also 250 feet in diameter. The length of 250 was used by the later Adena Hopewell to represent the Sun deity.

There were several of these clusters of earthworks around Chillicothe, Ohio that were 250 in circumference.  

     A unique work is situated in the little valley of "Black run," a small tributary of Paint creek, and is distant about fifteen miles from Chillicothe. It is indicated by the letter E.  The walls are composed of stones; but if ever regularly laid up, they are now thrown down, though not greatly scattered. The outlines are clearly defined, and can be exactly traced. The body of the work is elliptical in shape, its conjugate diameter being one hundred and seventy feet, its transverse two hundred and fifty feet. There is a single opening or gateway, fifty feet wide, on the south, where the walls curve outwards and lap back upon themselves for the space of sixty feet. The most remarkable feature of this singular work consists of five walls, starting within ten feet of the unbroken line of the elliptical enclosure, and extending thence northward, slightly converging, for the distance of one hundred feet. The lines of the outer walls, if prolonged, would intersect each other at the distance of two hundred and fifty feet. These walls are twenty feet broad at the ends nearest the enclosure, and ten feet apart. They diminish gradually, as they recede, to ten feet at their outer extremities. The western wall is nearly obliterated; the stones for the construction of all the "cabin" hearths and chimneys in the neighborhood having been taken from this spot. The western portion of the wall of the ellipse has also suffered from the same cause. The amount of stone embraced in the outer walls is considerable, probably sufficient to construct walls of equal length, six feet broad and eight feet high. They now exhibit but slight evidence of ever having been regularly laid up, and more resemble mounds of stones rudely thrown together. The stones have been removed from a section of the central wall, to the base; but we have been unable to ascertain that the operation disclosed relics of any kind. The wall of the body of the work appears considerably lighter than those last mentioned, and it is now quite impossible to determine whether it was ever regularly constructed. The stones cover a space fifteen or twenty feet broad, and are irregularly heaped together to the height of perhaps three feet. The work is overgrown with briers, bushes, and trees; which, when in leaf, completely hide its features from view, and render a satisfactory examination impossible. In the autumn or spring, the entire outline of the work is distinctly visible.
The purposes of this strange work are entirely inexplicable: its small size precludes the idea of a defensive origin. It is the only structure of the kind which has yet been discovered in the valleys, and it is totally unlike those found on the hills. The great "Stone Fort" on Paint creek is but two miles distant, and overlooks this work; both may be regarded as belonging to the same era, and as probably in some way connected with each other.

Sruce Hill Adena Stone Enclosure in Ross County, Ohio


"Spruce Hill" Serpentine Stone Work, Near Bourneville, Ross County, Ohio

 
     
This work occupies the summit of a lofty, detached hill, twelve miles westward from the city of Chillicothe, near the village of Bourneville. The hill is not far from four hundred feet in perpendicular height; and is remarkable, even among the steep hills of the West, for the general abruptness of its sides, which at some points are absolutely inaccessible. It is the advance point of a range of hills, situated between the narrow valleys of two small creeks; and projects midway into the broad valley of Paint creek, so as to constitute its most prominent natural feature. It is a conspicuous object from every point of view. Its summit is a wide and fertile plain, with occasional considerable depressions, some of which contain water during the entire year.


     The defences consist of a wall of stone which is carried around the hill, a little below the brow; but at some places it rises, so as to cut off the narrow spurs, and extends across the neck that connects the hill with the range beyond. It should not be understood by the term wall, that, at this time, anything like a wall of stones regularly laid up exists; on the contrary, where the line is best preserved, there is little evidence that the stones were laid one upon the other so as to present vertical faces, much less that they were cemented in place. At a few points, however, more particularly at the isthmus D, there are some indications of arrangement in the stones, tending to the belief that the wall here may have been regularly faced on the exterior. The appearance of the line, for the most part, is just what might be expected from the falling outwards of a wall of stones placed, as this was, upon the declivity of a hill. Upon the western, or steepest face of the hill, the range of stones covers a space varying from thirty to fifty feet in width, closely resembling the "protection walls" carried along the embankments of rail-roads and canals, where exposed to the action of rivers or large streams. But for the amount of stones, it might be taken for a natural feature,—the debris of the out-cropping sand strata. Such, certainly, is the first impression which it produces upon the visitor; an impression, however, which is speedily corrected upon reaching the points where the supposed line of debris, rising upon the spurs, forms curved gateways, and then resumes its course as before.
     Upon the eastern face of the hill, where the declivity is least abrupt, the wall is heavier and more distinct than upon the west, resembling a long stone-heap of fifteen or twenty feet base, and from three to four feet in height. Where it crosses the isthmus it is heaviest; and although stones enough have been removed from it, at that point, to build a stout division wall between the lands of two proprietors, their removal is not discoverable. This isthmus is seven hundred feet wide, and the wall is carried in a right line across it, at its narrowest point. Here are three gateways opening upon the continuous terrace beyond. These are formed by the curving inward of the ends of the wall for forty or fifty feet, leaving narrow passways between, not exceeding eight feet in width. At the other points, A and C of the plan, where there are jutting ridges, are similar gateways. It is at these points that the hill is most easy of access. At A is a modern roadway; at C is a pathway leading down into the valley of "Black Run." At B appears to have been a similar gateway, which for some reason was closed up; a like feature may be observed in the line D. At the gateways, the amount of stones is more than quadruple the quantity at other points, constituting broad, mound-shaped heaps. They also exhibit the marks of intense heat, which has in some instances vitrified their surfaces, and fused them together. Light, porous scoriae are abundant in the centres of some of these piles. Indeed, strong traces of fire are visible at many places on the line of the wall, particularly at F, the point commanding the broadest extent of country. Here are two or three small mounds of stone, which seem burned throughout. Nothing is more certain than that powerful fires have been maintained, for considerable periods, at numerous prominent points on the hill; for what purposes, unless as alarm signals, it is impossible to conjecture.
      It will be observed that the wall is interrupted for some distance at E, where the hill is precipitous and inaccessible. There are, as has already been remarked, several depressions upon the hill which contain constant supplies of water. One of them covers about two acres, and furnishes a supply estimated by the proprietor as adequate to the wants of a thousand head of cattle. Water is obtained in abundance at the depth of twenty feet.
      The area enclosed within this singular work is something over one hundred and forty acres, and the line of the wall measures upwards of two and a quarter miles in length. Most of the wall, and a large portion of the area, are still covered with a heavy primitive forest. Trees of the largest size grow on the line, twisting their roots among the stones, some of which are firmly imbedded in their trunks.
That this work was designed for defence, will hardly admit of doubt; the fact is sufficiently established, not less by the natural strength of the position, than by the character of the defences. Of the original construction of the wall, now so completely in ruins, we can of course form no very clear conception. It is possible that it was once regularly laid up; but it seems that, if such were ever the case, some satisfactory evidence of the fact would still be discoverable. We must consider, however, that it is situated upon a yielding and disintegrating declivity; and that successive forests, in their growth and prostration, aided by the action of the elements, in the long period which, must certainly have elapsed since its construction, would have been adequate to the total demolition of structures more solid and enduring than we are justified in supposing any of the stone works of the ancient people to have been. The stones are of all sizes, and sufficiently abundant to have originally formed walls eight feet high, by perhaps an equal base. At some points, substantial fence-lines have been built from them, without sensibly diminishing their numbers. It can readily be perceived that, upon a steep declivity, such as this hill presents, so large an amount of stones, even though simply heaped together, must have proved an almost insurmountable impediment in the way of an assailant, especially if they were crowned by palisades.
      In the magnitude of the area enclosed, this work exceeds any hill-work now known in the country; although the wall is considerably less in length than that of "Fort Ancient," on the Little Miami river. It evinces great labor, and bears the impress of a numerous people. The valley in which it is situated was a favorite one with the race of the mounds; and the hill overlooks a number of extensive groups of ancient works, the bearings of which are indicated by arrows on the plan.
Paint creek washes the base of the hill upon the left, and has for some distance worn away the argillaceous slate rock, so as to leave a mural front of from fifty to seventy-five feet in height. It has also uncovered a range of septaria, occurring near the base of the slate stratum; a number of which, of large size, are to be seen in the bed of the creek, at a. These, most unaccountably, have been mistaken for works of art,—"stone covers" for deep wells sunk in the rock. This notion has been gravely advanced in print; and the humble septaria, promoted to a high standing amongst the antiquities of America, now figure prominently in every work of speculations on the subject. The reason for sinking wells in the bed of a creek, was probably never very obvious to any mind. The supposed "wells" are simple casts of huge septaria, which have been dislodged from their beds; the cyclopean "covers" are septaria which have resisted the disintegrating action of the water, and still retain their places. Parallel ranges of these singular natural productions run through the slate strata of this region: they are of an oblate-spheroidal figure, some of them measuring from nine to twelve feet in circumference. They frequently have apertures or hollows in their middle, with radiating fissures, filled with crystalline spar or sulphate of baryta. These fissures sometimes extend beyond them, in the slate rock, constituting the "good joints" mentioned by some writers. The slate layers are not interrupted by these productions, but are bent or wrapped around them. The following cut illustrates their character.
