One of the principal characteristics of the Mogollon culture pattern is the relative abundance of ground and pecked stone artifacts, for the most part of a rather rough-and-ready nature. There can be little doubt that this is, in large measure, a heritage from their Cochise forebears, for often the same tool types are continued, almost without change, from preceramic into ceramic Mogollon horizons. Examples of such continuation are basin and slab metates and associated mano types, grinding slabs, pestles and boulder mortars, abrading stones, stone balls, and the universal hammer stones. Some of these artifacts are widespread in the Southwest in both time and space; others are specifically southern in their distribution. Data concerning the time and branch distribution of Mogollon ground stone artifacts are presented in Table 11 and Figure 8
