Zuñi In 1927 the leading archaeologists of the Southwest gathered at Pecos, New Mexico, and worked out a system of terminology.[74] An early stage characterized by a nomadic life with no knowledge of agriculture had been postulated although no direct evidence had been found. This hypothetical period was named _Basketmaker I_. The early semi-agricultural, semi-hunting culture which produced fine baskets but no pottery, and for which there was evidence, was called _Basketmaker II_. To the third and final phase, when pottery was made, the term _Basketmaker III_ was assigned. Clear-cut evidence for Basketmaker I has been lacking and the term is little used although the finds in the Tabeguache Caves may be attributed to this period. A simpler terminology than that proposed at the Pecos Conference has since been suggested and it will be used in this book.[110] The term _Basketmaker_ is applied to the people formerly assigned to Basketmaker II and their immediate successors are called _Modified Basketmakers_. The Basketmakers were widespread over the Southwest and remains of their culture have been found in Utah, Arizona, New Mexico, and Colorado. We know them best from the San Juan Drainage. It is probable that they really reached their highest development here, but we must also take into consideration the fact that here we have ideal conditions for the preservation of much normally perishable material, and this gives us far more information than is available for many sections of the country. Many Basketmaker remains are found in caves along cliff faces. The term cave, although widely used, however, is perhaps misleading, for it has a connotation of darkness and of deep enclosed places. Actually the so-called Basketmaker caves are fairly shallow rock shelters, worn in the rock by the action of water and wind, and open to the sun. In them are found ash and dust deposits which contain the bodies of the ancient inhabitants and their possessions.
