This thesis project presents a short archaeological history of what is currently known as the Pratt Complex and a comprehensive analysis of the Pratt artifact assemblages held at Wichita State University, the University of Kansas, and the Kansas State Historical Society. The purpose of this analysis is to provide as detailed a description of these Pratt-related materials as possible in the absence of comprehensive excavations or feature data. This provides the basis for defining the Pratt Phase and for outlining elements of continuing research that needs to be done.
