The publication in 1962 of Lew Binford s paper "Archaeology as Anthropology" is generally considered to mark the birth of processualism a critical turning point in American archaeology. In the hands of Binford and other young University of Chicago graduates of the 1960s, this "new" archaeology became the mainstream approach in the U.S. The realignment that the processualists proposed was so thorough that its effects are still being felt today. Predictably, processualism also spun off a number of other "isms," several of which grew up to challenge its supremacy.

The Powers Phase Project was a multiyear archaeological program undertaken in southeastern Missouri by the University of Michigan in the late 1960s and early 1970s. The project focused on the occupation of a large Pleistocene-age terrace in the Little Black River Lowland-a large expanse of lowlying land just east of the Ozark Highland-between roughly A. D. 1250 and A. D. 1400. The largest site in the region is Powers Fort-a palisaded mound center that - ceived archaeological attention as early as the late nineteenth century. Archa- logical surveys conducted south of Powers Fort in the 1960s...

It is difficult for today's students of archaeology to imagine an era when chronometric dating methods were unavailable. However, even a casual perusal of the large body of literature that arose during the first half of the twentieth century reveals a battery of clever methods used to determine the relative ages of archaeological phenomena, often with considerable precision.
Stratigraphic excavation is perhaps the best known of the various relative-dating methods used by prehistorians. Although there are several techniques of using artifacts from superposed strata to measure time, these...
