Abstract
The classification of projectile points in North America often emphasizes the shape and size of the haft element and not of the blade element. Emphasis on the haft element in classification is an advisable strategy because the blade element morphology and size tend to change during the use life of the specimen. This is exactly why the characteristics of projectile point blade elements such as retouch amount, size, and shape are useful for inferring characteristics of technological organization. Variability in retouch amount and location on projectile point blade elements is shown to be directly associated with prehistoric hunter–gatherer land use patterns.
INTRODUCTION
Hafted biface provisioning strategies (production, consumption, discard) have been shown to be directly related to artifact function and processing requirements for various tasks (Ahler 1971; Churchill 1993; Ellis 1997; Frison 1991; Hester and Green 1972; Odell and Cowan 1986; Tomka 2001; Truncer 1988). However, others have shown that hafted biface provisioning strategies are also directly related to human land-use practices and raw material availability (Andrefsky 1994, 2005; Daniel 2001; Flenniken and Wilke 1989; Greaves 1997; Hoffman 1985; Kelly 1988; Sassaman 1994; Tankersley 1994). This is particularly true of hunting and gathering populations, which often leave residential base camps for extended periods of time to acquire resources outside of a one- or two-day spatial range. Such tool makers and users must be equipped with an adequate supply of hafted bifaces while on the move or they must have the ability to resupply their tool kits while away.
