Scale and Time-Space Systematics in the Post-A.D. 1100 Mimbres Region of the North American Southwest

Time-space systematics for the end of the Classic Mimbres period and subsequent developments in southwest New Mexico are outlined, and the variable spatial scale of these processes is emphasized. The regional unity of the Late Pithouse and Classic periods began to break down around A.D. 1130, a time when disparate developments characterize different portions of the region. The Terminal Classic (ca. A.D. 1130 and later) represents the first steps toward significant and rapid changes and is seen primarily in the Mimbres Valley. The Postclassic Mimbres (ca. A.D. 1130–;1200), in the eastern Mimbres area, represents settlement changes after the depopulation of large Classic Mimbres villages. The later, though not well dated, Black Mountain phase in the southern part of the region refers to new styles of pottery and architecture, with ties to the south, including Paquimé.
