In his recently published paper on “The Archaeology of Central California I: The Early Horizon” Robert F. Heizer writes “it is possible to anticipate at least in the later Southwestern horizons, for which we have dendrochronologic dates, a direct cross-chronology between the Southwest and California in terms of actual year dates.“
Fourteen Californian shell types from Anasazi sites, ranging from Basketmaker II to Pueblo IV, have been listed. Nine of these fourteen types come from Basketmaker III sites, one also from Basketmaker II, indicating that they were already being made in California contemporaneously and probably considerably earlier. These Basketmaker examples thus establish a minimum dating for the types in California.
