In the front portion many large rocks are lying on the surface of the clay floor and others are imbedded in it; probably still others are entirely covered. Farther back the clay is mixed with gravel washed from the interior. This deposit is never entirely dry and in rainy seasons is quite muddy. The difficulty of removing or digging under the rocks, added to the certainty that water would be encountered before the bottom is reached, render useless any effort at complete excavation. The amount of refuse on the surface, however, is a good indication that such researches as would be possible in the upper layers, among the rocks, would disclose a large quantity of aboriginal remains of comparatively modern date.
GRAVES AT LAUGHLIN'S (17)
On the Laughlin goat ranch, 6 miles southeast of Waynesville, a high narrow ridge level along the top and sloping abruptly on each side extends northward from the hills on the right side of Roubidoux Creek and terminates in a vertical cliff. Bedrock projects on the top and on both sides, and vegetation is so scanty that the crest is almost a "bald."
On the summit of this ridge are seven cairns, the first one only a few feet from the edge of the cliff, the last one about 300 feet back, near where the ground begins to ascend toward the plateau. They are small, none more than 3 feet high, and all have a depression in the top where the stones have been thrown out from the center toward the outside by relic seekers and rabbit hunters.
In three of them flat stones remaining in place at parts of the margin indicate that an irregular square inclosure was constructed around the bodies, as in those examined at Gourd Creek. Possibly this feature existed in all of them at the time of their construction, but there was no evidence that any of them had been walled up like those at Sugar Tree Camp or the Devil's Elbow. Views of their present conditions are shown in plate 14.
KERR CAVE (17)
Near the site of Kerr's Mill, on Roubidoux Creek, 5 miles south-east of Waynesville, is a cave at the foot of a bluff, the entrance 60 feet above the bottom of the hill. Viewed from the outside it has the appearance of a rock shelter 40 feet wide and 45 feet deep. Above most of it the stratum forming the roof is 15 feet high; near the front the successive overlying strata project in a hollow curve until at the face of the bluff the drop from the ledge to the talus immediately beneath it is fully 50 feet.
At one side, near the rear, is a passage 5 or 6 feet wide, not visible from the front, extending back into the hill. Although the cave is usually dry, clean gravel in this passage shows that sufficient water flows through at times to prevent earth from accumulating; further evidence of which fact is found in the mud cracks of the floor and the ferns growing amid the rocks, large and small, which cover it.
The place could never have been occupied except for temporary shelter, and there is no evidence that even this use was made of it.
