Part 35

Considerable digging has been done for saltpeter, but except near the front it has been only superficial.

The top of the earth at the extreme rear of the cave is almost or quite as high as the roof at the front, which means that, if the bottom should be level, the thickness of this accumulated deposit is not less than 35 feet. As the dip is toward the rear and quite sharp, about 10 or 12 degrees, the earth here may well be much thicker than indicated.

Excavation would be tedious and costly, as it would be impossible to dispose of the dirt except by blasting a deep trench through the rock in front to make room for wheeling it out.

KILLIAN CAVES.--There are two of these, both on the west slope of Lookout Mountain. One is near Brandon, 6 miles south of Fort Payne. The entrance is a large sink hole on the side of the mountain, descent into which is difficult owing to the steepness and large rocks. At the bottom the water which flows in over the muddy floor from the slope above--several acres in extent--rushes into a hole choked with loose stones and disappears.

The second cave is about 3 miles northeast of Collinsville. Debris from the mountain has formed a wall across the entrance, which is naturally wide and high and opening out on a little flat in front. Some digging has been done for saltpeter at the front part of the cave, reaching about 30 feet back from the inner foot of the accumulation. In the pit thus formed water stands after every rain until it soaks away. Where it ends the "face" is about 5 feet high. On top, farther in, there is much travertine or stalagmite; in some places it extends entirely across the floor. In other places the floor is bare. There is constant drip, and in one room there is a little gully, where surface water in wet weather, entering from a small branch cave on one side, has cut an exit through the earth at the foot of the wall on the other side. The hole in which it disappears extends beyond the rays of a lamp, and a stone thrown in goes down a slope several feet in length. Very little working is needed to reduce any of the earth to soft, slippery mud, hence no excavation was possible.

MARSHALL COUNTY

FEARIN CAVE.--This is in a bluff on the right bank of the Tennessee River, 10 miles below Guntersville. It has three divisions. Shortly after passing the spacious entrance a branch turns to the right. In a few feet a wall is reached which can be scaled only with a ladder. Climbing this, a large chamber is reached, totally dark, and the home of innumerable bats whose "guano" covers the floor and fills the air with a stifling odor. This branch comes to light again more than a mile away on the side of the mountain.

Returning to the lower chamber and going back about 100 feet from the main entrance, a wall similar to the first is reached, above which is another large cave. Bats never inhabit this, and the floor is of loose dry earth. But no ray of daylight penetrates it, and as a great amount of saltpeter was made here during the War of 1812 scarcely any of the earth retains its original position. During the Civil War the floor of the lower or main cave was also dug up for making saltpeter and much of the leached earth piled in front of the cave. This acts as a dam against encroachment of the river except in the highest floods. There seems, however, to be a passage between the cavern and a spring under the river bank, for water appears on the floor as soon as it reaches the same height outside and the two surfaces maintain a constant level until the freshet subsides. On account of these facts no excavations were made.

HARDIN'S CAVE.--Nine miles below Guntersville, on the right bank of the Tennessee, is a ferry known as Honey Landing. It is at the lower end of a steep bluff which forms the river front of a high hill or mountain, as such elevations are called here. A few feet above high-water mark a narrow ledge or shelf projects, which can be reached only from a point on the side of the hill just above the ferry. About 100 yards from here the ledge reaches a cave, which has a high and wide entrance, with ample space for several families to live on a fairly level, well lighted floor. If the cave were dry, it would be an ideal primitive home. But water continually seeps down the hill above and falls over the roof at the entrance, while a gully through the cave and several minor washes, as well as the mud spread over the floor, show that a large amount of water flows through the cave in wet seasons and covers all the floor except an area some 15 feet in diameter. This is dry on top, but would be muddy at a depth of 3 or 4 feet, the level of the bottom of the gully, so no exploration was attempted.

WELBURN'S CAVE.--Six miles northeast of Guntersville is a cave in which many human bones have been found. It is only a burial place and could never have been used as a dwelling. The entrance, barely large enough to crawl into, is at one side of the bottom of a large sink hole due to the falling in of a cave roof. It receives all the rainfall of more than an acre and is nearly choked with mud and driftwood. It may have been somewhat larger at one time, as there is a tradition that a deer was chased through the cave, coming out at Bailey's Cave, a mile away. Within a few rods the water sinks into the earth, and the floor of the cave, rising beyond this point, is dry. It was on this dry earth, not in it, that the skeletons were found. The floor is uneven, at some places permitting a man to stand, and at others rising to within 3 feet of the roof. Explorations can not be made, as there is no method of disposing of the removed earth.

BAILEY'S CAVE.--This cave is 7 miles northeast of Guntersville. The entrance is high and wide and there is a large, well-lighted area within; but the cave is flooded every time Town Creek gets out of its banks. Bailey's Cave is the other end of Welburn's Cave, as persons have gone through the hill from one to the other.

BARNARD CAVE.--This cave, which is also called Alford's and is still more commonly known as Saltpeter Cave, is on the left bank of the Tennessee 10 miles below Guntersville and opposite the Fearin property. The entrance is at the foot of a bluff overlooking a strip of bottom land a fourth of a mile wide, but the opening is above any flood that has occurred since the country was settled. At the foot of the slope is a bayou filled with Tupelo gums. Between this and the river the ground can be cultivated.

The cave is so straight and the walls so smooth as to look like an artificial tunnel. The entrance is in plain view from a point 380 feet back, and the change of direction, even at that distance, is very slight. The saltpeter miners started at the entrance and removed all the earth lying from 3 to 6 feet higher than the present floor, which is nearly level. They carried their work along the surface of a stratum of gravel, sand, and clay, which is so compact as to be difficult to remove with a pick, and seems to belong to the stream which carved out the cavern. The "face" where they quit work is 5 feet high, and the earth is quite dry, breaking down in angular fragments and separating from the walls so freely as to leave no residue on them. Its original depth at any point, however, may be very easily ascertained by noting the different tints or shading of the wall rock, the lower part, which was protected by earth, being distinctly lighter in color than that above, which was exposed to atmospheric weathering and, for a time, to the smoky torches and candles of the workmen.

The distinct lamination of the saltpeter earth, as shown in the "face," proves it to have been laid down slowly and intermittently in still water. It could not be determined whether this was due to the river in flood periods, or to a gentle stream from the interior whose volume varied in accordance with weather conditions. There is also a small channel along the top of the earth, filled with gravel and sand, as if the overflow of a stream far back in the mountain had been diverted in this direction after the laminated deposits had become dry and settled.

The walls are 10 feet apart near the entrance, but are not more than 8 feet elsewhere and in some places the width narrows to less than 3 feet. They also have an inward slope at the bottom, so the cave is either shallow or else so narrow at no great depth as to be uninhabitable. This fact, and the character of the material deposited by the ancient drainage stream, make it hopeless to expect result from exploration.

MCDERMENT'S CAVES.--There are two caves 100 yards apart, in Brown's Valley, 11 miles southwest from Guntersville. The larger has a descent of 21 feet from the front to the general level of the first floor. All this part is well lighted. The drainage from several acres of the mountain side above pours over the roof at the entrance and runs down the inner slope. It has worn a gully, and the first level it reaches is quite muddy. Leaves and trash 3 or 4 inches deep are piled on and against the loose stones toward the side where the water seeks an outlet. It has worn a crooked channel along this side of the chamber, and falls into a hole which at a depth of 10 or 11 feet below the floor makes a turn and passes from sight. So it is certain that soft wet clay extends more than 30 feet below the level of the entrance. The drier deposits of this room have been extensively worked for saltpeter, and a much greater quantity of earth would have been removed but for the fact that masses of stalagmite, too thick to break off with a sledge hammer, and scores of columns, some of them 6 or 8 feet in diameter and many tons in weight, cover a considerable part of it. The first room is succeeded by several others, all of which are dry and of large size, but in total darkness, and the floors in all have been more or less disturbed in the search for niter. The general direction of the bottom is downward. The last floor is probably 50 or 60 feet lower than the entrance, and is reached by a slope on which it is difficult to retain a footing. In nearly every part the earth is covered by stalagmite, much of it so heavy that the miners could not remove it, but were compelled to dig under it as far as they could reach; and in no place is a rock floor to be seen.

The thickness of stalagmite on the floor, and the great size of the columns, is proof of their antiquity, while the depth of earth beneath must have been thousands of years in accumulating before the deposits began to cover them.

Excavations here, while quite desirable, would be very expensive. Much stalagmite would have to be blasted; upward of a thousand yards of earth moved, and all of it taken out of the cave, because there is no room for it inside. As a man can not push a wheelbarrow up such an incline, a trench must be cut through to the exterior slope; and as solid rock lies not more than 5 feet below the surface at any point, blasting would be necessary the rest of the way. The task is equal to opening a stone quarry.

The second cave on McDerment's place has a good opening. A trench 4 feet wide and 6 feet deep where the rock is thickest has been blasted out to make a level approach to the entrance. Masses of stalagmite on each side, sloping like solid rock from the walls, leave barely room for a man to walk for the first 30 feet. Here the walls recede somewhat, and a pit nearly 15 feet deep yawns before the explorer. After continuing for some distance with this depth, there is another drop of 10 feet which holds until the end of the cave is reached. This entire depression is due to the removal of earth for making saltpeter. It is evident that a vast amount of material has been carried out.

As in the first cave, excavation would be very difficult and expensive. All rock and earth would have to be carried up a steep grade, or a deep cut made to wheel it out. As the light is very dim at the first widening of the walls, it is not probable the space farther back would be occupied unless as a refuge.

Both caves were eroded by water running into the hill, and the end of each is abrupt, the roof being higher and the walls farther apart than at any point nearer the entrance. The original outlets are now filled with earth, and apparently have been so for ages.

FORT DEPOSIT CAVE.--Six miles below Guntersville the highway to Huntsville crosses the Tennessee River at Fort Deposit Ferry and passes out through a narrow valley between two bluffs. Less than 100 yards above the landing, on the north, or right, bank, is a large cave from which the spot takes its name; there being a tradition that it was used by General Jackson as a storage room for supplies during the Creek Indian war. On either side the bluff is vertical to the water's edge, making the cave now inaccessible except by boat. In front of the entrance the rock is worn in ledges which can be easily ascended.

The opening or mouth of the cave is oval in form, about 18 feet high and 15 feet wide. The sides are uneven, there being a projecting shelf on each side near the floor. At 40 feet from the opening these disappear, owing to the narrowing of the cavern. There is a gradual ascent of the floor toward the rear, the rise being about 2 feet in the first 60 and more rapid from that point onward. A thin deposit of dried mud on each side, where it escapes the feet of visitors, shows that the river enters the cave at times, but not to a depth that carries it back more than 25 feet. The present ferryman says the flood of 1867 is the only one which has reached so far within that period.

After clearing away the earth, roots, and rocks at the front, a straight vertical face at a distance of 18 feet from the entrance measured 91/2 feet at top and 5 feet at the bottom between the solid rock wall on each side, and was 4 feet 4 inches high. The floor was not of solid rock entirely across, there being a crevice less than 4 feet wide which was not cleaned out, because no one could have lived in it. About the middle of this bank (vertically) streaks of red earth, burned elsewhere, extended 31/2 feet out from the right wall; there was very little ashes and no charcoal mixed with it. Above this red the earth was dark like garden soil and contained a few shells and fragments of pottery, with a little charcoal and ashes; it had all been disturbed and apparently resulted from scraping the debris away from camp fires. Below this, the line of demarcation being very distinct, the earth was yellow and sandy, like river bottom land, and contained no foreign matter except roots of trees growing outside. Figure 23 shows a section on this line; the crevice is omitted from this and the subsequent illustrations.

At 20 feet in, a foot below the top of the dark earth, was some charred corn. The yellow earth became irregular, thinner, and higher against the side walls than at the center. (See fig. 24.)

At 22 feet the yellow earth had nearly run out, there being only a small amount against either wall, while the darker earth reached down into the crevice that opened in the narrow strip of rock floor. In the lower portion were mingled a few shells, pebbles, and specks of charcoal, as if it had been thrown there. Across the upper portion of the deposit extended fire beds, burned earth, ashes, shells, broken pottery, and occasionally a fragment of bone. (See fig. 25.)

At 24 feet it was found that what had been taken for a solid floor in the last section represented was only a large flat rock which had fallen into the crevice and wedged tightly. When this was passed the yellow earth reappeared, at a slightly lower level.

At 26 feet the yellow earth became mixed with red. It was excavated to a depth of 5 feet in the endeavor to discover the reason for this. As there was not the slightest trace of ashes or charcoal, the red admixture must be a natural result of staining by iron in some form and not due to heat. Above the yellow was the usual stratum of dark earth, containing culinary debris. In the central portion of this was a mass, sufficient to fill a wheelbarrow, of angular, unburnt fragments of limestone from 3 to 15 pounds in weight. On the surface of the dark earth were some ten or twelve fire beds, reaching from wall to wall, the edges overlapping and interlacing in so confusing a manner that the exact number could not be made out. (See fig. 26.) At this stage it appeared that the crevice, or at least its upper part, had been filled by river floods and a slight ridge of sand thrown across the mouth of the cave. The Indians, it seems, occupied both this ridge and the lower area behind it, throwing debris to the rear to fill up the depression instead of carrying it all to the outside. It is equally possible, however, that this waste was brought from points farther back and thrown here to fill and level the floor. These heavy fire beds came to an end at about 28 feet on the right and 29 feet on the left. A section at 28 feet is given in figure 27. At their inner margin, among the ordinary refuse characteristic of such deposits, were many fragments of human bones, including ulnas of two individuals, one much larger than the other. They plainly indicated cannibalism, as they were broken when thrown here. Besides the ulnas, there are pieces of ribs, scapula, tibia, and feet.
