Southwestern Pueblo pottery of the prehistoric periods has been studied, named with dozens of geographic appellations, and traced back from period to period with genealogic thoroughness. “And La Plata Black-on-White begat Red Mesa Black-on-White, and Red Mesa Black-on-White begat Escavada Black-on-White, and Escavada Black-on-White begat Gallup Black-on-White.” But the family tree of prehistoric Southwestern walls has not been cultivated with the ardor of the potsherd horticulturist; the relation of roots to branches has been largely conjectural.
