The chronology and morphology of Pinto series projectile points in the Great Basin and the Mojave Desert have been the subject of much debate. Split-stemmed points have been found in both early and late contexts associated with dates spanning the late Paleoindian and Archaic Periods. This lack of temporal specificity may relate to differences in regional morphology through time coupled with misidentification of other point types as Pinto series. These issues are discussed using a collection of 170 Pinto series points from the distal portion of the Old River Bed delta of northwestern Utah. The research presented here examines the distributional, chronological, and quantitative differences between the Pinto series and other split-stemmed projectile points of the Great Basin. The results indicate the comparatively robust Pinto form is primarily found on the southern and eastern fringes of the Great Basin in earlier contexts than that of the more northerly and gracile Gatecliff Split stem point.
