ABSTRACT
By about 1500 years ago, the Developed Northwest Coast Pattern was present from the northern California coast to Yakutat Bay in Alaska. Almost everywhere, this stage appears to be a continuation of the previous one and blends into the ethnographic period. It is the easiest to interpret, given the abundant ethnographic records. In spite of these advantages, as well as the large number of sites excavated with components that date to the last 1500 years, there are still some outstanding questions.
