Systems Analysis and the Folsom-Midland Question

This paper discusses the use of systems analysis in the formulation of archeological taxons, with special reference to projectile point types. The latter are viewed as material manifestations of specific cultural subsystem trajectories. To illustrate the concept, hypothetical models of projectile point trajectories are presented, and variation in production techniques defined. The analytic approach is then applied to the practical problem of classifying Folsom and Midland points. Superficial similarity between these point types masks significant technological variations which do exist and are made explicit by the systems approach. It is suggested that differences in the attributes of the original flake blanks best account for variation between the Folsom and Midland trajectories. The hypothesis is offered that the complex Folsom production technique was selected purposely to achieve a more efficient utilization of lithic material.
