The excavation on the eastern side began with a trench 25 feet wide. When this had been carried about the same distance toward the wall, rocks and earth rolled and washed in from the outside were encountered on the right, the side toward the mouth of the cavern. These reached from the bottom to the surface, and were continuous with the bank of talus. As results had been meager along here, the sides of the trench were turned to the northward and northwestward. The entire trench was 43 feet long and varied in width from 30 feet in the central parts to 18 feet at the extreme northern end. The left face reached, in its entire length, nearly to the drain; on the right side the eastern wall of the cavern was uncovered for 15 feet. It embraced nearly all the area not previously dug by others, except a triangular space at the east side of the entrance, filled with large stones, as just stated.
Near the middle of the excavated area was a heap of large fallen rocks, fully a carload in all; some of them imbedded in the muck, others barely penetrating the surface of the latest deposits. Ashes lay under and between all of them, proving this side also had been inhabited before the first of them had become loose, and that occupancy was practically continuous until the last one had fallen. The inmates, recognizing the danger, may have knocked these down.
The greatest depth of ashes found in any part of the excavation was 7 feet; but it may have been greater previous to any disturbance; nor does this include such as may be present in the muck. There were unbroken layers as much as 8 inches thick covering spaces 5 to 10 feet across; many smaller, intact patches; and numerous masses, from a peck to a bushel in volume, removed from fire beds elsewhere. Charcoal among them showed that bark and dead wood, principally oak, was the main reliance for fuel.
The wrought objects found were flints, mostly broken or of rough finish; very many small fragments of pottery; mortars made of sandstone slabs; hammerstones or pestles; bone perforators; mussel shells, some pierced for suspension or for attachment of a handle, some with outer surfaces and edges dressed for use as spoons; hematite ore, in the rough or rubbed to procure paint. There was a great abundance of bones from animals used for food, mostly deer, though elk, bear, many smaller mammals, turtles, tortoises, turkeys, and other birds were well represented. Singularly enough, when the plentiful supply of fish in all the streams of this region is considered, none of their bones or scales were found, although the ashes would have preserved them perfectly. Nor were there many burned rocks, in view of the amount of pottery and the number of bones which showed that they had been boiled. Perhaps such stones had crumbled or were thrown outside when near disintegration.
There is a consensus of belief, or at least of statement, in the neighborhood that many human skeletons have been dug out close to the east wall. In the only part reached during this work—which took in about all that had not been searched by others—rocks lay along the wall, so large and so numerous that no graves could have been dug behind or between them. By careful and persistent questioning it was established that skeletons had been found in two places and a detached jaw in another.
A human skull, which was very soft and fell to pieces when uncovered, was found on, and slightly pressed into, the muck at a point 15 feet from the wall; there were no other bones about it, though a rough stone hammer, whose presence was probably accidental, lay close by. A single human molar was lying among some ashes.
These were the only human remains found during the work, except two adult femurs of different individuals, and fragments of a skull and some other bones from a child and from an infant, all of which lay close to the wall where they had been thrown and slightly covered by parties previously working here.
As the depth of the wet material on the rock floor of the eastern side of this cavern is unknown, interesting results might be obtained by a careful examination of it; but this can not be made until a ditch is dug through it of sufficient depth to drain it thoroughly.
Slight investigation outside the entrance showed a large amount of broken bones, pottery, and flint; and this dump may contain even more material than was found in an equal volume in the cavern. But in addition to the rocks of all sizes broken off from the cliff, there were also many which had rolled down from the hillside above; and all these were so interlaced with roots as to make digging very difficult and unsatisfactory. Consequently further exploration at this site was deemed undesirable.
Pointed bone and antler implements from Gourd Creek Cave are shown in plate 4. A shell knife, a bead from a fragment of sea shell, and types of flint arrowheads appear in plate 5.
