that no such patterning could be detected. According to Reed and Metcalf (1999:83), “It <br />would appear that the diversity and lack of chronological and spatial patterning is real, and <br />that it is time to move beyond wishful thinking about obtaining an orderly projectile point <br />chronology for the area.” <br />In opposition to their earlier observations, Metcalf and Reed (2011:131-133) <br />identified diagnostic points found in association with the Paleoarchaic, Early and Middle <br />Archaic period sites, which are listed in Table 2. Importantly, they have identified a new <br />type called “Narrow Series Points” that are characterized by broad, shallow side-notches, <br />sometimes grading into a stemmed appearance, and are narrow, convex-to-triangular in <br />overall shape. They also have a subset defined by shallow notches and a basal shape <br />ranging from convex to very slightly concave. These have been dated ca. 7100–5900 cal BP <br />(ibid.:132). <br />Table 2.

The key distinguishing feature between formal <br />and informal is the amount of labor invested in the construction. Formal structures exhibit <br />heightened investment of labor and evince a proclivity toward prolonged or repeated <br />occupation. Semi-subterranean structures are typical manifestations of formal structures. <br />Informal structures are characterized by expedient construction and a short term occupation. <br />25
