Cynthia Irwin-Williams [1936-1990]


Definition: American archaeologist Cynthia Irwin-Williams was at Eastern New Mexico State University when she conducted important interdisciplinary archaeological research at Salmon Ruins. She also excavated at the early site of Valsequillo, Mexico, although the original (uranium) dates were wildly off and the site is still somewhat controversial. Her best contribution to the archaeology of the American southwest, apart from the hundreds of students she taught, was her attempt in the 1960s to synthesize data from pre-pueblo sites throughout the southwest into the PICOSA (Pinto-Cochise-San Jose) or "Southwest Archaic" concept.
