They Walked Together Paisley Cave in Oregon provides some of the earliest evidence for humans in North America. Jenkins et al. (p. 223 ) provide a wide variety of additional evidence of early human occupation of this site, including a series of radiocarbon ages extending back to nearly 12,500 radiocarbon years ago (about 14,500 calendar years ago). The find includes examples of projectile points representative of the Western Stemmed Tradition dating to about 11,100 radiocarbon years ago. The Western Stemmed Tradition has been thought to have evolved after the dominant Clovis technology, but the find suggests that the two cultures overlapped in time.
Smith et al. (2013) provided important new information concerning the ages of a variety of projectile point types found in the Great Basin. Two of their interpretations, however, deserve further discussion. Smith et al. (2013) concluded that the Nicholarsen (or Nicolarsen) Cache contains both dart and arrow points. However, our application of methods developed by Hildebrandt and King (2012) to distinguish dart and arrow points, indicates that the Nicholarsen Cache contains arrow points exclusively. In addition, we suggest that the two ca. 6,800-year-old “Elko-Eared” points identified by Smith et al. (2013) are Large Side-notched points.
