The skeletons were badly preserved, but we were able to gather several skulls and some of the larger bones.
The floor material was so hard that only by means of heavy iron bars could we break through it.

As it was impracticable for us to make complete excavations, the number of rooms each mound contained cannot be stated.

There were in the immediate neighbourhood of Cave Valley at least ten or twelve separate groups, each of which had from four to eight rooms on the ground floor.

The entire district is richly studded with mounds.

On an excursion three or four miles down Piedras Verdes River I saw several groups of mounds, some of which, no doubt, contained many objects of antiquity.
