Spatial distribution of Paleoindian radiocarbon-dated occupations in Canada and the United States by degrees west longitude and degrees north latitude. (A) Radiocarbon-dated occupations from the period 13,299–13,000 calBP. (B) Radiocarbon-dated occupations from the period 12,999–12,700 calBP. (C) Radiocarbon-dated occupations from the period 12,699–12,400 calBP. Circles show locations of a radiocarbon-dated occupation, squares show the location of two overlapping radiocarbon-dated occupations, and triangles show the location of three overlapping radiocarbon-dated occupations.
