Although there were well-built trincheras in all the surrounding arroyos, there were no traces of either tools or pottery on that hill.
On the western slope of the Sierra de Nacori, on top of another knoll, and at an elevation of 6,400 feet, we found numerous rude ground plans, some of which showed rubble walls fifteen inches thick.

They formed groups of four or five apartments, each ten by twelve feet.

But on the north side of that summit there was a larger plan, nearly eighteen feet square; however, the outlines of the entire settlement were not distinct enough to enable us to trace its correct outlines.
Many fragments of pottery lay about, but neither in number nor in interest could they be compared with those found near the ruins in the southwest of the United States, for instance, near the Gila River.

Some of the potsherds were one-third of an inch thick, and large enough to show that they had been parts of a large jar.

They were made of coarse paste, either gray or brown in colour.
