It would appear that this cave was utilized as a place of shelter at irregular intervals by Indians in tolerably recent times; that at least one of those found, perhaps all three, had died or been killed during a somewhat protracted sojourn; and that only a slight covering of earth, if any at all, had been placed over them.
Two similar caves are within 8 or 10 miles, but were not visited.
EDMONSON COUNTY
Mammoth Cave.—For miles from the entrance saltpeter workers have dug down to a level where the amount of loose rock rendered further excavation too expensive. In many places walls of stone are piled against the sides of the cavern. They were among the earth that was removed and have been so piled to get them out of the way.
As far back as "Chief City," 3 miles from the mouth of the cave, the floor is littered with fragments of canes (reeds) and saplings, which, from the appearance of the ends, were broken, twisted, or bruised off with blunt tools like stone hatchets. Most of those remaining are lying on massive loose rocks now forming the floor, though the ends of some are seen projecting from beneath stones much larger than two men can lift. It is possible the latter have recently slid or slipped from higher up the slopes, but the indications are that they have dropped from the roof since the time of these early explorers. If this be the case, it points to a considerable antiquity for the remains, because no such downfalls are known to have occurred since the cave was first explored by white men.
So much work has been done about the entrance of late years for improving the approaches that excavation would be useless, even if allowed, unless carried to a depth of more than 20 feet. Such work would greatly interfere with the plans of the management.
White's Cave.—This is about three-fourths of a mile from Mammoth Cave. The entrance, quite small, is near the crest of a ridge, and the floor descends abruptly. Only a narrow chamber exists within reach of daylight, and the cave is wet all the time a short distance back.
Colossal Cave.—It is said to be 4 miles from Mammoth Cave, but is really only a little more than 2 miles. The present entrance is entirely artificial, the descent to the floor being about 120 feet. The original entrance was in a crevice which explorers descended by means of ropes. It is said that another entrance is known to one man who, however, has to crawl a long distance.
Salt Cave.—This is 4 miles from Mammoth Cave, though belonging to the same company. The entrance is at the bottom of a conical sink hole draining about an acre. Not much water runs into the cave from this cause, as the surface slopes outward from the margin except on one side, where a ridge leads to the hills. A spring which comes out near the top of the sink falls over a ledge at the bottom into the entrance to the cave. It is said that this water soaks into the ground within a few rods and that just beyond are large, dry rooms, well adapted for habitation, which formerly contained many evidences of aboriginal occupation. Exploration is impossible now, as the entrance was effectually closed some years ago by throwing in logs, brush, rocks, and earth, in order to protect the formations from relic hunters. The water from the spring falls directly on and flows into this, and can not now be turned aside. Even if it could, all excavated material would have to be carried up a steep slope and deposited in the field surrounding the sink hole.
Dixon's Cave.—It is supposed, with good reason, that this was at one time connected with Mammoth Cave. It can be easily entered, through a large crevice, where the surface rock has fallen in. Approach to the bottom is down a steep and rugged slope of about 60 feet vertically. Within, no earth is visible, it having been entirely removed by saltpeter miners, who left the rocks piled in great rows from side to side across the cavern.
