![]() ![]() Analyses of sediments from other reservoirs should generate further discoveries of uncarbonized seeds or other biological remains (e.g., pollen, phytoliths, diatoms, snails) and refine our understanding of prehistoric water storage facilities throughout the world.Ī pesar de que los sistemas de canales de irrigación a gran escala han sido asociados con la cultura prehistórica Hohokam (200–1450 d.C.) del centro-sur de Arizona, los estanques constituyeron unafuente esencial de almacenamiento de agua para uso doméstico en aqueilas zonas del Desierto de Sonora alejadas de arroyos о corrientes perennes. The high number of Lemna seeds indicates that water may have been stored on a long-term, perhaps perennial, basis. 1200–1450) Hohokam site (AZ AA:3:32 ) yielded uncarbonized seeds of an aquatic plant belonging to the genus Lemna (duckweed). Sediments recovered with a hand-driven bucket auger from an earthen reservoir at a large Classic-period (ca. This assumption of seasonal water storage is a hypothesis that should be tested rather than uncritically accepted by archaeologists. ![]() Interpretations of seasonal water storage in prehistoric Hohokam reservoirs are often based on direct analogy with the historic Tohono O'odham (formerly called the Papago). 200–1450) of south-central Arizona, earthen reservoirs were essential for domestic water storage in areas of the Sonoran Desert away from perennial streams. Although large-scale canal irrigation technology is commonly associated with the prehistoric Hohokam (A.D. ![]()
