Cairns (1), (2), and (3) were thoroughly excavated.
Cairn (1)
This, the farthest north, was about 16 by 17 feet within the original limits. When the outer loose rocks were removed there was disclosed a wall of flat stones on the natural surface, so laid as to form an inclosure apparently intended to be practically square. It measured, across the center, from outside to outside, about 14 feet from north to south by 12 feet from east to west. The north and south walls were straight, the others outwardly curved. The approximate outline is shown in figure 1. In most parts the wall was only one stone high; in a few places there was another rock laid up. Over and within this wall had been piled loose stones, ranging in size from small pebbles to fragments of 150 pounds in weight, to form a heap whose original height was about 2 feet.

When all these were cleared away the space within the wall was found to measure 9 feet in each direction. Three feet from the middle of the west wall was a fragment of a child's skull lying on the undisturbed angular gravel which forms the natural surface on this ridge except where a small amount of recently decayed humus may be held by rocks and roots. Halfway between the center and the north wall was the top of an adult skull, with three fragments of long bones. These, which were much gnawed by rodents, were in black earth, evidently the former home of some burrowing animal.
A foot north of the infant's skull were small remnants of an adult's skull, probably belonging with the piece first found. There were also some scraps of animal bones, much gnawed.
Cairn (2)
This measured from 16 to 18 feet across to the outer edge of the loose stones, and about 30 inches high. Under the top rocks was a rough wall similar to that in Cairn (1), but all the sides were nearly straight. The outline is given in figure 2. The outside measurements, across the center, were 15 feet each way. There were more stones in this wall than in the first; mostly there were two, and in some places three, superposed.
