MINES AND MINING TECHNIQUES OF CHALCHIHUITES CULTURE

The Chalchihuites culture of the Colorado-Suchil river drainage of western Zacatecas began about A.D. 100 as a somewhat evolved and belated Early Preclassic colonization of simple agriculturalists. By the Alta Vista phase (ca. A.D. 350-550) it had assumed the role of a much more complex society. A great expansion of population occurred. This transition was very rapid and present evidence supports the hypothesis that highly organized social groups colonized the area in order to exploit the mineral resources located there. Extensive mining operations, coupled with self-supporting agricultural patterns, characterize the zenith of the period. The extent of mining was much more than local consumption could possibly require and therefore points to the economic dependence of the exploitative organization upon the high cultures farther south and southeast. This paper reviews the 1963 and 1965 surveys of the Alta Vista mining operations and draws some conclusions about the character of the society which sponsored them. © 1968 Society for American Archaeology.
