From other regions of the Americas, there are other suggestions of early man and ancient cultures. J. L. Giddings’ Palisades culture, on mountainside benches of Cape Krusenstern, Alaska, north of Bering Strait, may be old. It appears considerably older than the Denbigh Flint Complex, south of the Strait, which may go back from 4,500 to 5,000 years.[86] And in South America early man is represented at such sites as El Jobo, in Venezuela;[87] an unpublished radiocarbon date from this region is rumored at about 16,000 years. The coming decade should bring further refinements in radiocarbon dating, as well as the development of newer techniques such as the Rosholt “uranium-daughter” products and obsidian hydration measurements. With or without the aid of these dating methods, livelier activity of archaeologists south of the border should soon give us more information about early man in Latin America. THE MORE IMPORTANT SITES OF EARLY MAN The listing on the three next pages, which goes no further than 1948, is not exhaustive. There is room for argument over a number of the finds; but the arrangement of the materials in columns provides a rough perspective. The sites are listed in order of discovery. The symbols indicate one or more occurrences: Occurrence of the saber-toothed cat, tapir, giant beaver, or extinct armadillo is not indicated. Finds that seem problematical or not definitely associated with other finds are shaded. Sandia points were found with the five extinct mammals indicated in the Sandia cave and below the Folsom.
