Love Riddles, Couple Formation, and Local Identity in Eastern France
The purpose of this article is to show how specific aspects of the popular culture of Lorraine (eastern France) can be linked to distinctive features of the region's historical demography after the Thirty Years' War. It examines two customs associated with courtship: the dâyage, an exchange of riddle-like verses between groups of men and women at winter wakes, and the dônage, mock banns of marriage called by young men on the first Sunday of Lent.…
The Full-Glacial Environment of the Northern Seward Peninsula, Alaska, Reconstructed from the 21,500-Year-Old Kitluk Paleosol
Paleoenvironmental conditions are reconstructed from soils buried under volcanic ash ca. 21,500 years ago on the Seward Peninsula. Soil development was minimal, reflecting the continuous regional deposition of loess, which originated from river floodplains and the exposed Chukchi shelf. Cryoturbated soil horizons, ice wedges, and ice-lens formation indicate a permafrost environment and mean annual temperatures below −6° to −8°C. Shallow active la…
The Largest Known Maars on Earth, Seward Peninsula, Northwest Alaska
The Espenberg Maars on the northern Seward Peninsula of Alaska were formed by a series of Pleistocene basaltic eruptions through thick permafrost. The maars were excavated as much as 300 m into older lithologies; ranging from 4 to 8 km in diameter, they are the four largest known maars on earth. Hydromagmatic eruptions which derive water from ground ice are evidently extremely explosive. The high heat capacity of ice in permafrost modulates the s…
Emergent Marine Record and Paleoclimate of the Last Interglaciation along the Northwest Alaskan Coast
The last interglacial high sea-level stand, the Pelukian transgression of isotope substage 5e, is recorded along the western and northern coasts of Alaska by discontinuous but clearly traceable marine terraces and coastal landforms up to about 10 m altitude. The stratigraphy indicates that sea level reached this altitude only once during the last interglacial cycle. From the type area at Nome, to St. Lawrence Island in the Bering Sea, to the east…
Late Quaternary Lacustrine Pollen Records from Southwestern Beringia
Sediment cores from three lakes in the Upper Kolyma region, northeast Russia, provide the first well-dated continuous record of late Quaternary vegetation change from far southwestern Beringia. The oldest pollen zone, tentatively assigned to the Karginsk (mid-Wisconsinan) Interstade, indicates an Artemisia shrub tundra with Pinus pumila , Betula , and Alnus at mid- to low elevations. With the onset of the Sartan (late Wisconsinan) Stade, Pinus di…
The role of situational factors in disciplinary judgements
This study examined the effects of four situational factors on the severity of punishment chosen by a manager following a rule infraction. Two attributes of the offender, gender and performance history, and two outcomes of the infraction, physical damage and personal injury, were combined within a scenario evaluated by 421 graduate business students in a 2 × 2 × 2 × 2 ANOVA design. Results indicated strong main effects for performance history, ph…
Middle Pleistocene age of the Nome River glaciation, northwestern Alaska
During the middle Pleistocene Nome River glaciation of northwestern Alaska, glaciers covered an area an order of magnitude more extensive than during any subsequent glacial intervals. The age of the Nome River glaciation is constrained by laser-fusion 40 Ar/ 39 Ar analyses of basaltic lava that overlies Nome River drift at Minnie Creek, central Seward Peninsula, that average 470,000 ± 190,000 yr (±1σ). Milligram-size subsamples of the lava were d…
Old Crow Tephra Found at the Palisades of the Yukon, Alaska
A 20-cm-thick volcanic ash layer at the Palisades along the Yukon River is geochemically correlated with the Old Crow tephra. A buried organic and wood-rich layer above the Old Crow tephra probably records the last interglaciation. The recognition of the Old Crow tephra provides the first chronologic information on the age of the thick sequence of Pleistocene sediments at the Palisades, an important ice-age mammal site in central Alaska and a key…

Canyon Creek: A Late Pleistocene Vertebrate Locality in Interior Alaska
The Canyon Creek vertebrate-fossil locality is an extensive road cut near Fairbanks that exposes sediments that range in age from early Wisconsin to late Holocene. Tanana River gravel at the base of the section evidently formed during the Delta Glaciation of the north-central Alaska Range. Younger layers and lenses of fluvial sand are interbedded with arkosic gravel from Canyon Creek that contains tephra as well as fossil bones of an interstadial…
Dated wood from Alaska and the Yukon: Implications for Forest Refugia in Beringia
Postulations on the existence of forest refugia in parts of Beringia during the last glacial have been, in large part, based on ambiguous evidence. Existing data on radiocarbon-dated and identified fossil wood and macrofossils from Alaska and northwest Canada are synthesized here and are augmented by results of palynological studies in an effort to show the persistence of some, and total extinction of other, tree and large shrub species. Possible…
An Anvilian (Early Pleistocene) Marine Fauna from Western Seward Peninsula, Alaska
Cover sediments of the York Terrace exposed near the California River, western Seward Peninsula, Alaska, yield mollusks, ostracodes, and foraminifera that lived during the Anvilian transgression of early Pleistocene age. The fossiliferous sediments lie at the inner edge of the York Terrace, a deformed wave-cut platform that extends eastward from Bering Strait along much of the southern coast of Seward Peninsula. The seaward margin is truncated by…
Sea Level History in Beringia During the Past 250,000 Years
This paper attempts to relate current knowledge of sea-level history in Beringia to the Broecker-van Donk “Termination” concept of climatic and sea-level history. The Einahnuhtan transgression is thought to represent Termination III, which according to Broecker and van Donk, took place about 225,000 y.a. The Kotzebuan transgression is thought to represent a positive fluctuation that modulated the generally falling sea level during the ensuing 100…
Middle Pleistocene Mollusks from St. Lawrence Island and their Significance for the Paleo-Oceanography of the Bering Sea
Drift, evidently of Illinoian age, was deposited on St. Lawrence Island at the margin of an ice cap that covered the highlands of the Chukotka Peninsula of Siberia and spread far eastward on the continental shelf of northern Bering Sea. Underlying the drift on the northwestward part of the island are mollusk-bearing beds deposited during the Kotzebuan Transgression. A comparison of mollusk faunas from St. Lawrence Island, Chukotka Peninsula, and …

The Potassium-Argon Dating of Late Cenozoic Rocks in East Africa and Italy [and Comments and Reply]
A technique for the potassium-argon dating of high potassium feldspars of less than 50,000 years age is described. The technique is applied to the obtaining of high precision ages in the time-range 60,000-2,000,000 years. Sufficient data are presented to show that the time-scale of Plio-Pleistocene glaciations is greater than 10 years and that the time-scale of hominoids capable of fashioning tools by the working of stone is at least 1.75 10 year…
Tundra Rodents in a Late Pleistocene Fauna from the Tofty Placer District, Central Alaska
Describes remains of the arctic ground squirrel, collared and brown lemmings, and the narrow-skulled vole collected 1956-1961 in or near the Sullivan mining pit. Topography, vegetation, and mining history are outlined, as are the stratigraphy and age of the unconsolidated deposits in which the fossils were found. The rodents, all typical tundra forms, are not now in the Tofty area which has been forested at least 6800 yr. Apparently, they represe…
Geology of the Imuruk Lake area, Seward Peninsula, Alaska
The Imuruk Lake area is underlain by metamorphic rocks of Paleozoic age, granitic rocks of probable Late Jurassic or Early Cretaceous age, and sediments and lava flows of late Cenozoic age.The Paleozoic metamorphic rocks include schist of several types assignable to Eskola's green-schist facies, gneiss assignable to Eskola's amphibolite facies, and metalimestone.The schist unit includes rocks that are older and younger than the metalimestone unit…
Some Characteristics of the Climate in Forest and Tundra Regions in Alaska
Discusses, as basis for paleoclimatic reconstruction, the relationship of climate to three major vegetation types: coastal Sitka spruce - hemlock forest, interior white spruce - birch forest, and tundra. These types are also represented in late Cenozoic fossil plant assemblages found in western Alaska. The vegetation types reflect annual temperature differences shown in data from 78 weather stations: forest stations record more than 130 days abov…
