AbstractA phytolith record from Monte Oscuro, a crater lake located 10 m above sea level on the Pacific coastal plain of Panama, shows that during the Late Pleistocene the lake bed was dry and savanna-like vegetation expanded at the expense of tropical deciduous forest, the modern potential vegetation. A significant reduction of precipitation below current levels was almost certainly required to effect the changes observed. Core sediment characteristics indicate that permanent inundation of the Monte Oscuro basin with water occurred at about 10,500 14C yr B.P. Pollen and phytolith records show that deciduous tropical forest expanded into the lake’s watershed during the early Holocene. Significant burning of the vegetation and increases of weedy plants at ca. 7500 to 7000 14C yr B.P. indicate disturbance, which most likely resulted from early human occupation of the seasonal tropical forest near Monte Oscuro and the development of slash-and-burn methods of cultivation.

AbstractField investigations at Dugway Proving Ground in western Utah have produced new data on the chronology and human occupation of late Pleistocene and early Holocene lakes, rivers, and wetlands in the Lake Bonneville basin. We have classified paleo-river channels of these ages as “gravel channels” and “sand channels.” Gravel channels are straight to curved, digitate, and have abrupt bulbous ends. They are composed of fine gravel and coarse sand, and are topographically inverted (i.e., they stand higher than the surrounding mudflats). Sand channels are younger and sand filled, with well-developed meander-scroll morphology that is truncated by deflated mudflat surfaces. Gravel channels were formed by a river that originated as overflow from the Sevier basin along the Old River Bed during the late regressive phases of Lake Bonneville (after 12,500 and prior to 11,000 14C yr B.P.). Dated samples from sand channels and associated fluvial overbank and wetland deposits range in age from 11,000 to 8800 14C yr B.P., and are probably related to continued Sevier-basin overflow and to groundwater discharge. Paleoarchaic foragers occupied numerous sites on gravel-channel landforms and adjacent to sand channels in the extensive early Holocene wetland habitats. Reworking of tools and limited toolstone diversity is consistent with theoretical models suggesting Paleoarchaic foragers in the Old River Bed delta were less mobile than elsewhere in the Great Basin.

In the excavation of Pendejo Cave (FB 9366) near Orogrande, New Mexico, 16 friction skin imprints were found in five stratified zones on clay nodules, baked at over 120°C. After careful analysis, expert dermatoglyphologists determined that these imprints had positive primate characteristics. The imprints are probably of human origin, since no other primates are known to have existed in prehistoric New Mexico. Eight of the imprints occurred in three well-dated zones falling in the late Pleistocene. These zones have direct radiocarbon dates between 12,000 and 37,000 B.P. In addition to their association with radiocarbon determinations, the prints come from three of 24 stratified zones, intensively studied by geologists and pedologists, that are dated in sequence by 34 other radiocarbon determinations acquired from four different laboratories. The imprints are associated with a column of over 35,000 paleontological specimens and more than 15,000 botanical remains. These specimens indicate Pleistocene changes and supply evidence of human transportation and modification of various materials. The prints are also associated with artifacts, ecofacts, features of human construction, and human remains. The imprint specimens therefore provide evidence of Pleistocene human occupation in the New World.

Molluscs, sediment lithology, and published sub-bottom profiles are used to deduce sea levels, outline the influence of glacially induced crustal displacement, and reconstruct the paleoenvironment of the northeast Pacific late Quaternary coastline. Geo-spatial modelling shows subaerially exposed land that could have been inhabited by plants and animals, and also coastally migrating early North American peoples. Ice-free terrain, present by at least 13 790 ± 150 14C years BP, a land bridge, and edible molluscs are identified. Queen Charlotte Islands (QCI) late Pleistocene coastal paleogeography may assist in explaining the biogeography of many terrestrial plant and animal species along the broader northeastern Pacific margin and provide evidence for researchers seeking late Pleistocene – early Holocene glacial refugia. Late Pleistocene – early Holocene coastlines that are not drowned and that may harbour early archaeological sites are identified along the western QCI, where migrants probably first travelled and the westernmost British Columbia mainland, where the effects of glacial ice were reduced.

Radiocarbon dates together with geoarchaeological, soil, and lithic analyses are presented to describe archaeological site 35-CS-9 in Bandon Ocean Wayside State Park, Oregon, northwestern USA. One of the few Oregon middle-Holocene coastal sites that includes sediments and artifacts dating to the early Holocene and possibly to the late Pleistocene, it was recorded in 1951 and surface surveyed by archaeologists in 1975, 1986, and 1991, but its depth and antiquity were not tested. In February 2002, we studied the site's stratigraphy and sediments and described 8 strata from the aeolian surface to bedrock at 350 cm depth. Soil samples taken from a cut bank for texture classification, particle size analysis, pH, carbon content, and chemical analysis suggested that the site represented a complete history of Holocene deposits. Excavation of 2 test units in August 2002 uncovered substantial lithic and charcoal remains that confirm a protracted middle-Holocene occupation and suggest that human occupation began in the early Holocene. Charcoal recovered at 235–245 cm dated to 11,000 14C BP, and the deepest lithic artifact was recovered in a level at 215–225 cm. Whether the human occupation was continuous throughout the Holocene, and whether it began in the early Holocene or in the late Pleistocene, can only be determined with further excavations.

Radiocarbon Chronology

Alaska is commonly viewed as a gateway between the Old and New Worlds, and as such, figures prominently in most models of the peopling of the New World. With a growing number of archaeological sites dating to the terminal Pleistocene, Alaska might be expected to provide direct evidence bearing on the colonization of the Americas. Based on 27 site components with 114 radiocarbon dates, this paper discusses the archaeological record of late Pleistocene Alaska, organized around the characteristics and chronology of three complexes: the microblade-bearing Denali complex, the Nenana complex, and the Mesa complex. This paper shows that the archaeological record of late Pleistocene Alaska is quite diverse, and not lacking in controversy and conflicting interpretations. In addition, this period of archaeological diversity coincides with the Younger Dryas climatic event. However, none of the reliably dated sites is older than the earliest evidence of human occupation further south in the Americas. Despite this, evidence from DNA studies points strongly to a north-central Asian homeland for Native Americans, upholding Alaska as the point of entry into the New World. Suggestions are offered, then, as to why the Alaskan record remains silent about the initial peopling of the New World.
