Two Decades of Debate on Meadowcroft Rockshelter
Since the publication of the first of more than fifty internally consistent radiocarbon dates from Meadowcroft Rockshelter (36WH297), intense and sometimes acrimonious controversy has swirled around the timing of the initial human occupation of this deeply stratified site. Critics of a late Pleistocene presence at this locality have questioned its stratigraphy, floral and faunal associations, the “character” of its earliest artifact assemblage, a…
Never Say Never Again
Tankersley and Munson (1992) reiterate that the early and, perhaps, some of the later Meadowcroft Rockshelter radiocarbon dates may be contaminated by anthropogenically derived coal or dissolved coal by-products. Their allegations are assessed in light of available data and rejected. Presently, there is no evidence whatsoever for particulate or nonparticulate contamination of any part of the Meadowcroft Rockshelter radiocarbon chronology
Radiocarbon Analyses from Cincinnati, Ohio, and Their Implications for Glacial Stratigraphic Interpretations
Detailed analysis of a site near Cincinnati, Ohio, shows that 14 C ages of samples in a single geologic unit can have a range of several thousand years and ages from different stratigraphic units can overlap. At the Sharonville site, four 14 C samples from organic silt below glaciogenic deposits have an inverted chronologic sequence, suggesting contamination, but nevertheless they indicate the silt was deposited before 27,000 yr B.P. A stump clus…
The Meadowcroft Rockshelter Radiocarbon Chronology 1975-1990
Ever since the publication of the first of more than 50 internally consistent radiocarbon dates from Meadowcroft Rockshelter (36 WH297), controversy has been generated by frequent assertions that the dates older than 11,000 B.C. have suffered particulate or nonparticulate contamination. Data bearing on these assertions are assessed in the light of accelerator mass spectroscopy (AMS) dates provided by Oxford University. The weight of all data take…
The Antiquity of Tlingit Settlement on Admiralty Island, Southeast Alaska
A series of 29 radiocarbon dates from 11 sites on Admiralty Island span the last 3,200 calendar years. Although our research corroborates many of the results of de Laguna's (1960) earlier work in the area, we find the Tlingit settlement pattern to be at least 1,600 years old, significantly older than previously believed. Dating of a wooden fish weir demonstrates that mass harvesting of salmon has an antiquity of at least 3,000 years
Interstadial Conifer Wood from Northern Maine
Conifer wood, probably spruce ( Picea sp.), of middle Wisconsinan age (29,200 ± 500 yr B.P.) was recovered from late-glacial lake sediments from Upper South Branch Pond, Maine. If the wood was derived from a local source, deglaciation of part of northern New England is suggested for this time. The occurrence also has implications for understanding the problem associated with radiocarbon dating of bulk lake sediment containing small amounts of org…

Paleosols and prehistoric populations in the high plains
Excavations in 1980–1981 at sites (32MZ319 and 32MZ380) along Cinnamon Creek Ridge in the Little Missouri River Badlands of McKenzie County, North Dakota, unexpectedly revealed at each locality the presence of one or more deeply buried paleosols with associated cultural materials. At both sites, 32MZ319 and 32MZ380, multiple paleosols are present, each of which is terminated by an episode of aeolian deposition. Fifteen radiocarbon dates on these …
Dating of Holocene Stratigraphy with Soluble and Insoluble Organic Fractions at the Lubbock Lake Archaeological Site, Texas
The Lubbock Lake site, on the Southern High Plains of Texas, contains one of the most complete and best-dated late Quaternary records in North America. A total of 117 14 C dates arc available from the site, determined by the Smithsonian and SMU Laboratories. Of these dates, 84 have been derived from residues (humin) and humates (humic acids) of organic-rich marsh sediments and A horizons of buried soils. Most of the ages are consistent with dates…

Radiocarbon Ages from the Lubbock Lake Site
Forty-eight additional radiocarbon ages became available for Lubbock Lake (Southern High Plains of Texas) during the period 1981-1984. A new but unreliable radiocarbon age is available from Stratum 1 (deposition ending about 11,000 years B.P.; Clovisage occupation). Thirty-three new radiocarbon ages are available from Stratum 2 and suggest the following refinements to the previously established radiocarbon chronology for the deposit: (1) the init…
Radiocarbon Ages From The Lubbock Lake Site, 1950-1980
The Lubbock Lake site is a well-stratified archaeological locality on the Southern High Plains of Texas. It contains a thick sequence of late Quaternary deposits with associated soils and cultural, faunal, and floral remains. Sixty-sevenradiocarbon ages-thus far are availa?le from the site, providing a well-dated chronology spanmng the past 11 ,000 years.Radiocarbon ages were determined on a variety of materials including wood, charcoal, shell, b…
Yes Virginia, It Really is That Old
All of the presently available and processed data from Meadowcroft Rockshelter indicate that the radiocarbon dates for middle and lower Stratum IIa are not discordant with either the associated fauna, flora, and artifacts or with the known geological history of the Cross Creek drainage. Consequently, it is reiterated that the earliest occupations at this locality still represent the best evidence recovered to date for the presence of pre-Clovis o…
Meadowcroft Rockshelter — Retrospect 1977
Meadowcroft Rockshelter is a deeply stratified multicomponent site in Washington County, southwestern Pennsylvania. The eleven well defined stratigraphic units identified at the site span at least 16,000, and perhaps 19,000 years of intermittent occupation by groups representing all of the major cultural stages/periods now recognized in northeastern North America. Throughout the extant sequence, the site served as a locus for hunting, collecting …

Late Cenozoic Paleoclimates of the Gaap Escarpment, Kalahari margin, South Africa
The Gaap Escarpment is a dolomite cuesta demarcating the southeast margin of the Kalahari. Since Miocene-Pliocene times, thick masses of lime tufa have repeatedly accumulated at several points along this escarpment, and four regional sequences are described. These allow discrimination of six major depositional complexes, commonly characterized by basal cryoclastic breccias or coarse conglomerates that reflect frost shattering and torrential runof…

Radiocarbon Dates and Late-Quaternary Stratigraphy from Mamontova Gora, Unglaciated Central Yakutia, Siberia, U.S.S.R.
A fine exposure of perennially frozen ice-rich silt and associated flora and vertebrate fauna of late-Quaternary age exists at Mamontova Gora along the Aldan River in central Yakutia, Siberia, U.S.S.R. The silt deposit caps a 50-m-high terrace and consists of three units. An upper layer 1–2 m thick overlies a 10–15-m-thick brownish to black silt layer. The lower silt layer is greenish to gray and about 15 m thick. All the silt is well sorted with…

Vegetation and Associated Environments during the past 14,000 years near Moulton Pond, Maine
Pollen influx and percentage diagrams were prepared from an 11.4 m core from Moulton Pond, Maine. The pond basin was deglaciated about 14,000 y. a., after which it was located on an island in a sea of subarctic character until about 12,400 y. a. when the surrounding area emerged from the sea. The terrestrial vegetation was tundra until about 10,000 y. a. A change in the tundra vegetation is synchronous with the emergence from the sea, but synchro…
Holocene Environmental Changes in the Alpine Zone, Northern San Juan Mountains, Colorado
Cores from five high alpine basins in the northern San Juan Mountains show several fluctuations in lithology. Typically, peats are interbedded with coarser clastic sediments or else woody peats alternate with fibrous peat. Twenty 14 C dates provide radiometric control. Sediment rates averaged about 2.5 cm/100 yr but varied at the different sites between 1.19 and 50 cm/100 yr. Rates were lower during the middle of the Holocene. Basal radiocarbon d…
Smithsonian Institution Radiocarbon Measurements VIII
This list includes samples completed to July, 1972. All samples are counted for at least 2500 min., and X 2 analyses are made on 100-min. print-outs. Errors quoted are 1 σ , derived from sample, background, and NBS oxalic acid standard measurements, adjusted where appropriate for small-sample dilution
Smithsonian Institution Radiocarbon Measurements VII
This list includes those samples dated between December 1968 and July 1971. Samples before SI-617 were completed before the laboratory was dismantled in April 1969 for renovations in the Smithsonian Institution Building. Samples beginning with SI-617 were dated after December 1970, following re-establishment of the laboratory in new quarters

Interstadial Conifer Wood from Northern Maine
Conifer wood, probably spruce ( Picea sp.), of middle Wisconsinan age (29,200 ± 500 yr B.P.) was recovered from late-glacial lake sediments from Upper South Branch Pond, Maine. If the wood was derived from a local source, deglaciation of part of northern New England is suggested for this time. The occurrence also has implications for understanding the problem associated with radiocarbon dating of bulk lake sediment containing small amounts of org…
