The earliest period represented at these sites is known as the _Georgetown_. The estimated dates are from 500 to 700 A. D.[50] Some archaeologists do not agree, and feel that 700 A. D. is the earliest date which may be given for the first Mogollon settlements in New Mexico.[99] During Georgetown times dwellings were small, roughly circular, pit houses which were entered by inclined passageways. A fire pit lay midway between the center of the room and the entrance. Roofs were supported by a main pole in the center of the structure and secondary poles along the walls. One larger pit house was found at Harris Village which, it is thought, may have been used for ceremonial purposes. It did not contain the deflector, sipapu, or benches which characterize most Pueblo kivas. It differs from the Georgetown domiciliary structures not only in size but in the greater length of the entrance passage and the possession of a straight front wall. Most pottery was undecorated. Only four sherds of painted pottery, which consisted of a crude gray ware with broad red lines, were found. The predominant types were a plain buff or brown ware and a polished red ware such as were found at the SU site. A few of the former fall in the category of textured pottery. This is pottery which has been embellished through techniques, such as scoring, incising, or punching, which change the character of the surface. There are no corrugated types in the early Mogollon, but a few pieces have banded necks, or have been scored. Textured pottery became increasingly common in later periods. Metates were made of unshaped stone blocks and were basin-shaped. Projectile points were short and broad stemmed. Large stemmed blades and stemmed drills were also made. Pipes were made of clay. They were short and were formed in one piece. Little is known of the physical type of the people and their burial customs, since only one grave has been found which may be attributed to this period. This contained the skeleton of an adult male with a slightly deformed skull who had been buried beneath the floor of a Georgetown house at Starkweather Ruin. THE SAN FRANCISCO PHASE Following the Georgetown in New Mexico comes the _San Francisco_ stage for which the dates 700 to 900 A.D. have been tentatively suggested.[50] A few datable logs have been found in structures assigned to the latter part of the period. The approximate age is given in round numbers with the terminal date as 900, although two logs gave dates of 927. The terminal date for the Georgetown and the beginning date for the San Francisco stage are by no means firmly established.
