Oshara tradition

Oshara Tradition, the northern tradition of the earlier Picosa culture, was a Southwestern Archaic tradition centered in the area now called New Mexico and Colorado. Cynthia Irwin-Williams developed the sequence of Archaic culture for Oshara during her work in the Arroyo Cuervo area of northwestern New Mexico. Irwin contends that the Ancestral Puebloans developed, at least in part, from the Oshara.^[1]
