Archaic Triangles from the Abbott Farm Complex (Custer 2001)
There has been an effort to physically distinguish Archaic triangles from later Woodland triangles at the Abbott Farm Complex. Stewart (1998) states that a “healthy percentage” of Archaic triangles can be distinguished from Late Woodland triangles by “1) a patterned approach to the pressure flaking of bases, and 2) the asymmetrical aspect of the basal edge angle.” In addition, they exhibit “finer workmanship, symmetry and thinness than later types” (Wall et al. 1996: 10). Katz (2000) on the other hand, presents data that suggest that Archaic through Early Woodland triangles are difficult to distinguish from Late Woodland triangles.
