in march, 1766, john jennings, a philadelphia merchant, going down the ohio with a cargo of goods for fort de chartres, illinois, notes in his journal that he stopped for an hour near “a large rock with a cave in it,” some twenty-five miles below the mouth of the wabash river. the earliest record of a homeseeking pioneer who came to the cave-in-rock country and there began an overland trip into illinois dates back to about 1780, when captain nathaniel hull, of massachusetts, appeared at what later became ford’s ferry. “he and several other young men,” writes governor john reynolds in his pioneer history of illinois, “descended the ohio to a point near ford’s ferry on that river [for a while known as hull’s landing and later as robin’s ferry] and came across by land to kaskaskia.... at this day the indians were not hostile as afterwards, so that hull and party escaped through the wilderness without injury.” nor had any white man as yet practiced piracy on the lower ohio.
victor collot, a french engineer, is one of the first writers who stopped at the cave and published a brief description of it. he knew of its existence long before he arrived, for his book, a journey in america, shows that he had planned to stop at the “big cave,” and did so in the summer of 1796 when he went down the river to new orleans.
a few months later the place was visited by andrew ellicott, then on his way to natchez for the purpose of determining the boundary line between the united states and spain. an entry in his journal, dated december 15, 1796, shows he “dined at the great cave ... one of the greatest natural curiosities on the river.”

on april 16, 1797, francis baily, the english astronomer, stopped there. his journal of a tour in the unsettled parts of north america contains a few pages on the “big cave.” among other things he says, “its entrance was on a landing-place. it had somewhat the appearance of an immense oven. we entered it and found the sides very damp.... we beheld a number of names cut in the sides of the cave, which in this solitary place, and cut off as we were from society, gave us a degree of pleasure to look over.” baily apparently heard of no outlaws during his short stay. this probably was due to the fact that his visit was made at a time when the cave was very damp, as is frequently the case in spring. had he appeared later, he might not have survived to tell of his interesting travels in america, for during the greater part of the year 1797 the place was occupied by the notorious mason family.
perrin du lac, in his travels through the two louisianas, writes that he embarked at pittsburgh, april 22, 1802, “in a pirogue thirty feet long and three feet broad” and that a few weeks later he stopped at the cave. he says “it is considered one of the greatest natural curiosities in north america.”
the first detailed description of cave-in-rock ever printed, as far as now known, appeared in one of the earliest editions of zadok cramer’s the ohio and mississippi navigator and was republished in the appendix of journal of a tour, 1805, by thaddeus m. harris without credit to cramer.
thomas ashe, an unreliable english traveler, wrote an account of cave-in-rock shortly after the cramer or the so-called harris description was published, and at a time when reports of some of the early robberies that had been committed there were still in fresh circulation.
25
his book entitled travels in america performed in 1806, contains a chapter of fabrications headed “cave in the rock, ohio bank, september, 1806.”
in july, 1807, christian schultz, then a young man, started from pittsburgh down the ohio in a flatboat. he arrived at “the cave in the rock” about october 1, continued his trip to new orleans, and returned, via ship, to new york. in his travels on an inland voyage, he devotes a few pages to the cave, saying, among other things:
“it is a very curious cavern.... i could not help observing what a very convenient situation this would be for a hermit, or for a convent of monks.... i have no doubt that it has been the dwelling of some person or persons, as the marks of smoke and likewise some wooden hooks affixed to the walls sufficiently prove. formerly, perhaps, it was inhabited by indians; but since, with more probability, by a gang of that banditti, headed by mason and others, who, a few years ago, infested this part of the country and committed a great number of robberies and murders....”
fortesque cuming, an unprejudiced englishman, wrote in his tour to the western country that the cave is “one of the finest grottoes or caverns i have ever seen.” this interesting traveler, in january, 1807, proceeded to maysville, kentucky, by boat, and from there made horseback trips to central kentucky and ohio. returning to pittsburgh, he started, on may 7, down the ohio in a flatboat for new orleans. from old bruinsburg, a few miles above natchez, he visited old greenville. in this town about three years before, one of the cave-in-rock outlaws had been convicted under unusual circumstances and hanged and buried in an
26
unusual manner. when traveling by boat cuming always carried a few skiffs in order to get ashore more easily. on may 18, 1807, a few minutes after passing the head of cave-in-rock island, he landed at what is known as cave spring, a cave-like opening a few hundred yards above cave-in-rock from which a strong spring of water constantly flows. this crevice in cave-in-rock bluff is about nine feet high, three feet wide, and extends back some forty feet. cuming at first mistook it for the famous cave, as has been done by more than one traveler since his day. in his sketch pertaining to his visit to cave-in-rock he writes:
“rowing along shore [below cave spring] with the skiff, we were soon undeceived as to that’s being the rocking cave, as a third of a mile lower down, one of the finest grottoes or caverns i have ever seen opened suddenly to view, resembling the choir of a large church as we looked directly into it. we landed immediately under it and entered it. it is natural, but it is evidently improved by art in the cutting of an entrance three feet wide through the rock in the very center, leaving a projection on each hand, excavated above to the whole breadth of the cavern, the projections resembling galleries.... it is crowned by large cedars, and black and white oaks, some of which impend over, and several beautiful shrubs and flowers, particularly very rich columbines, are thickly scattered all around the entrance.... standing on the outside, the appearance of some of the company at the inner end of the cave was truly picturesque, they being diminished on the eye to half their size, and removed to three times their real distance.
“there is a perpendicular rocky bluff just opposite the lower end of cave island, about two hundred yards
27
above the cave, where the river narrows to less than half a mile wide, forming a fine situation for fortification.”
thomas nuttall probably was the last distinguished traveler who came down the ohio in a flatboat and commented on the cave. in his journal of travels into the arkansa territory he states that he and his party left shawneetown december 14, 1818. after floating a short distance they came up with three other flatboats and, lashing them together, proceeded upon an all-night journey. he further comments: “the river is here very wide and magnificent and chequered with many islands. the banks of battery rock, rock-in-cave, and other places are bold and rocky with bordering cliffs. the occidental wilderness appears to here retain its primeval solitude; its gloomy forests are yet unbroken by the hand of man; they are only penetrated by the wandering hunter and the roaming savage.”
the early western travelers already cited, and a number of their contemporaries and followers who saw the cave, published descriptions or references that agree in the main, but each, in his own way, was evidently more impressed by certain of its various features than were some of the others who visited the place. a few speculated upon it as an indian temple of prehistoric times. some commented upon it from a geological standpoint. a number were especially interested in the names they found carved on the walls; some in the trees that grew around the opening. others dwelt upon it as a rendezvous of outlaws.
for what various purposes the cave may have been used in prehistoric times by mound-builders and indians, or even cave dwellers, is a question for archaeologists
28
and ethnologists. there is far less physical evidence to indicate a previous presence of robbers and counterfeiters than there is to prove that the place was inhabited by prehistoric man. a rusty home-made dagger blade and a part of a counterfeiter’s mold are the only relics that point toward the outlaw occupancy. on the other hand, five well-defined mound sites in the level fields above cave-in-rock bluff, and the many flint and stone implements picked up during the past century in and near the cave indicate beyond doubt the former presence of indians and mound-builders. in april, 1918, robert l. yeakey, while spading his garden on this bluff, unearthed a carved stone image, six inches high and four inches wide, weighing two pounds, six ounces, representing a man in squatting position. the probability that the image is an idol gives strength to the inference that the cave was used as a temple some time in the prehistoric past.
the mounds are additional evidence to this effect. these were opened many years ago and have since been plowed over often. each contained, it is said, from five to ten human skeletons. the bodies had been placed in a stone-walled sepulcher that was covered with flags of stone a few inches thick, over which a circular mound of earth was thrown. the fact that each of these mounds contained a number of skeletons, apparently placed there at one time, leads many to the conclusion that a battle, or battles, must have been fought in or near the cave and that all, or some, of the dead were buried together. scientists advance a plausible explanation of this: “we know not if these burials indicate famine, pestilence, war, or unholy sacrifice. we can only conjecture that they were not graves of persons who had died a natural death.” because of
29
the cave’s temple-like form and its proximity to these old mounds, it appears more probable that they were erected in connection with the ceremony of “unholy sacrifice” than for any of the three other suggested causes.
the harris description of the cave, written about 1803, refers to it as “the habitation of the great spirit.” some thirty years later, edmund flagg, in the far west, written after his visit to “rock-inn-cave,” says: “like all other curiosities of nature, this cavern was, by the indian tribes, deemed the residence of a manito, or spirit, evil or propitious, concerning whom many a wild legend yet lives among their simple-hearted posterity. they never pass the dwelling place of the divinity without discharging their guns (an ordinary mark of respect) or making some other offering propitiatory of his favor.”
from official records we learn that the section of the country in which cave-in-rock is embraced was sold, in 1803, to the united states by the kaskaskia tribe. in 1818, when the sale was confirmed by the same indians and the three other tribes then constituting the illinois confederacy, it became unchallenged government property. thus, when the masons, the harpes, and other early outlaws held forth there, it was still in the indians’ territory.
from a geological standpoint, the cave is evidently nothing more than a prosaic hole in a limestone bluff. in neither the main cave nor the crevices above are there any stalactites or stalagmites, but an incrustation resembling such a formation occurs here and there on the walls. in 1818, henry r. schoolcraft, in his personal memoirs, says: “the cave itself is a striking object for its large and yawning mouth, but to the geologist
30
presents nothing novel.” collot, in 1796, expressed the opinion that “it is an excavation made in the rocks by the continual beating of the flood.” in a report published in 1866, a. h. worthen, director of the geological survey of illinois, states that “the limestone (st. louis limestone) is quite cherty and the cave has probably been formed by the action of water percolating through crevices of the rock and by the eroding influences of the atmosphere.” neither of these explanations is satisfactory. no other has been found. cave-in-rock has the appearance of a section of a large cave that was formed by an underground stream in some remote geological age, and later disconnected, by upheavals, from the other parts of the subterranean passage. some of the other parts may still exist. sulphur springs cave, four miles southwest of equality, may be one. bigsby cave, eight miles north of cave-in-rock, may be another. hardin county is besprinkled with many sinkholes, the outlets of which are unknown. the “big sink,” four miles north of the cave, covers about one hundred acres. cave-in-rock may have been an outlet for some of these sinkholes until upheavals made such drainage impossible.
in early days the virgin forests retarded, to a great extent, the water of the heavy rains, and as a result floods were less frequent and less severe. it is probable that when cave-in-rock and the country about were covered with trees the place was damper than now, for the water then slowly seeped down from the tree-covered surface. nevertheless, it was sufficiently dry to serve as a good shelter not only for outlaws, who frequently occupied it, but also for men and women going down the river in flatboats.
today it is comparatively dry, except during the
31
spring and shortly after a heavy rain. practically all the water running through the cave now comes from a narrow crevice in the rear, which drains a small sinkhole in the surface. through this opening, as already stated, much soil has been deposited in the back part of the cave during the past fifty years. nature has made practically no changes in the cave itself since its discovery by white men, but the landscape has been affected by the removal of the large trees that once shaded its mouth. a decrepit sycamore, an ash or two, a few small maple trees, some scrub cedars, and some virginia creeper constitute the only vegetation now growing around the opening.
the travelers who visited cave-in-rock in flatboat days gave the place more time and thought than did those who appeared after the introduction of steamboats. the new orleans, or orleans, which was the first steam-propelled boat to make a trip from pittsburgh to new orleans, passed it in 1811. not until fully five years thereafter was the practicability of navigating the ohio by steamboats satisfactorily demonstrated. local tradition has it that the james monroe, coming down in 1816, was the first steamboat to land at the cave. thomas nuttall, who appeared on the scene two years later, was, as already stated, one of the last distinguished men who floated down the river in a flatboat and commented on the place. leisure was an inseparable feature of flatboat travel. with the coming of steamboats the lingering of travelers along the river became a thing of the past. after 1820 comparatively few boats of any kind stopped at the cave. boats became more numerous, but whether propelled by steam or oars, they traveled not only faster but through a country rapidly increasing in population,
32
and passengers and crew stopping in this section found better shelter elsewhere. but cave-in-rock was ever pointed out as a place that “in days gone by” had been the den of flatboat robbers. counterfeiters and other outlaws, however, operated in the neighborhood until as late as 1832.
the earliest record of a professional artist making a sketch of the cave dates back to may, 1819, when major stephen h. long came down the ohio on the steamer western engineer, on his way to his rocky mountains exploring expedition. in his notes on “cave-inn-rock or house of nature” he gives a description of the cave, and says that samuel seymour, the official artist of the expedition, “sketched two views of the entrance.” edwin james’s account of this expedition contains many of seymour’s pictures, but none of places east of the mississippi. efforts made in washington to locate his original sketches were without success.
edmund flagg, a traveler, journalist, and poet, who lived the greater part of his life in louisville and st. louis, spent a short time at the cave in 1836, while on a steamboat trip gathering material for his book, the far west. he gives some of the history of the outlaws of “cave-inn-rock” and then describes the cave and the island. he says the place furnishes “a scene of natural beauty worthy an inman’s pencil” and that “if i mistake not an engraving of the spot has been published: a ferocious-looking personage, pistol in hand, crouched at the entrance, eagerly watching a descending boat.”
