Tree-ring Dating of the Little Ice Age Maxima of Arolla Glaciers (Valais, Switzerland)
Little Ice Age (LIA) glacier variations are well constrained in the Alps, partly thanks to an unparalleled body of historical sources. When absent, tree-ring dating can be used to obtain accurate chronological information on glacier maxima. To do so, it is necessary to focus on the trees that immediately bordered the former maximum extent reached by the glaciers in historical times. Here, we present tree-ring dating results for newly sampled wood…
Datation dendrochronologique des maxima du Petit Âge Glaciaire des glaciers d’Arolla (Valais, Suisse)
Les variations des glaciers lors du Petit Âge Glaciaire (PAG) sont bien connues dans les Alpes, en partie grâce à un ensemble inégalé de sources historiques. Lorsque ces dernières sont absentes, la dendrochronologie peut être utilisée pour obtenir des informations chronologiques précises sur les maxima des glaciers. Pour ce faire, il faut cibler les arbres situés en limite de l’extension maximale atteinte par les glaciers à l’époque historique. I…
The glacier advance at the onset of the Little Ice Age in the Alps
The term ‘Little Ice Age’ (LIA) is classically used to define a period of repeated and extensive glacier advances during the last millennium. In the meanwhile, this term is also used to address the period of relatively low temperatures between the Medieval Climate Anomaly (MCA), or Medieval Warm Period, and present-day warming. The end of the LIA is generally set to the mid or late 1800s CE, however, the published onset dates of the LIA are more …

A study of the Würm glaciation focused on the Valais region (Alps)
During the Last Glacial Maximum (LGM), the glaciation in the European Alps reached maximum ice extent. We already simulated the steady states of the Alpine ice coverage for several climate drivers in Becker et al. (2016) and heighten in this article such studies for the Swiss Valais region. To this end, we employ the Parallel Ice Sheet Model (PISM), which combines the shallow ice approximation (SIA) with basal sliding elements of the shallow shel…

A proposal for an atmospheric paleocirculation model for NE Anatolia during the Last Glacial Maximum
Multiple cosmogenic nuclides document complex Pleistocene exposure history of glacial drifts in Terra Nova Bay (northern Victoria Land, Antarctica)
Geomorphological and glacial geological surveys and multiple cosmogenic nuclide analyses ( 10 Be, 26 Al, and 21 Ne) allowed us to reconstruct the chronology of variations prior to the last glacial maximum of the East Antarctic Ice Sheet (EAIS) and valley glaciers in the Terra Nova Bay region. Glacially scoured coastal piedmonts with round-topped mountains occur below the highest local erosional trimline. They represent relict landscape features e…
First results of cosmogenic dated pre-Last Glaciation erratics from the Montoz area, Jura Mountains, Switzerland
Cosmogenic nuclides and the dating of Lateglacial and Early Holocene glacier variations
Multicentury glacier fluctuations in the Swiss Alps during the Holocene
Subfossil remains of wood and peat from six Swiss glaciers found in proglacial fluvial sediments indicate that glaciers were smaller than the 1985 reference level and climatic conditions allowed vegetation growth in now glaciated basins. An extended data set of Swiss glacier recessions consisting of 143 radiocarbon dates is presented to improve the chronology of glacier fluctuations. A comparison with other archives and dated glacier advances sug…
Luminescence Dating of Sediments from the Luthern Valley, Central Switzerland, and Implications for the Chronology of the Last Glacial Cycle
The advancing glaciers of the last glacial maximum either eroded or deeply buried older sediments in the Swiss Alpine Foreland. However, part of the Swiss Plateau was not covered by ice and is therefore an excellent area for investigating climate and environmental change during the Upper Pleistocene. Repeated fluvial sequences can be studied in several pits along the Luthern Valley. The chronological framework is based on lithostratigraphy, polle…
The Alps with little ice
Glacially deformed pieces of wood, organic lake sediments and clasts of reworked peat have been collected in front of Alpine glaciers since AD 1990. The palaeoglaciological interpretation of these organic materials is related to earlier phases of glacier recession surpassing that of today's shrunken glaciers and to tree growth and peat accumulation in the valleys now occupied by the glaciers. Glacial transport of the material is indicated by wood…
Can We Use Cosmogenic Isotopes to Date Stone Artifacts
Two chert artifacts from the region near Luxor, Egypt have yielded concentrations of cosmogenic 10 Be that allow calculation of nominal exposure ages of 326,000 and 304,000 years. Both artifacts are flakes that were collected atop limestone benches of the Eocene Thebes Formation which form cliffs along the west side of the Nile. The site is at elevation 240 m and is about 15 km from the Nile. Tools associated with these artifacts can be attribute…
Alpine Evidence for Atmospheric Circulation Patterns in Europe during the Last Glacial Maximum
The configuration of Alpine accumulation areas during the last glacial maximum (LGM) has been reconstructed using glacial–geological mapping. The results indicate that the LGM ice surface consisted of at least three major ice domes, all located south of the principal weather divide of the Alps. This implies that the buildup of the main Alpine ice cover during oxygen isotope stage (OIS) 2 was related to precipitation by dominant southerly atmosphe…

Calibration of the 14 C Time Scale Beyond 22,000 BP
The conventional 14 C time scale between 11,500 and 22,000 sidereal years has been calibrated by TIMS U/Th dates for corals. Only a few studies have been made for the time beyond this range. Obtaining samples suitable for numerical dating or estimating the reservoir correction of the 14 C dates has been difficult, but we do not have these problems with TIMS U/Th dating of interstadial and interglacial lignite, because reservoir corrections are un…
Minimal Extension Phases of Unteraarglacier (Swiss Alps) During the Holocene Based on 14 C Analysis of Wood
Tree trunks and wood fragments in minerotrophic fen peat that accumulated as the result of a jökulhlaup in the outwash plain of Unteraarglacier were radiocarbon-dated using conventional ß-counting. Different pretreatment methods were tested on two wood samples to determine the reliability of our dates. We dated the wood compounds after extended acid-alkali-acid treatment, as well as extraction of cellulose and lignin. The results of the samples P…

Radiocarbon Age of the Laacher See Tephra
The Laacher Sec Tephra (LST) layer provides a unique and invaluable time marker in European sediments with increasing importance because it occurs just before the onset of the Younger Dryas (YD) cold event. As the YD begins ca . 200 calendar years after the LST was deposited, accurate determination of the radiocarbon age of this ash layer will lead to a more accurate age assignment for the beginning of the YD. On the basis of 12 terrestrial plant…
Talgenese im Quartär
State-of-the-art knowledge of valley-forming processes in the Alps and the southern and, especially, the northern foreland is presented. Based on the stratigraphy of the Quaternary infill of formerly broadly and deeply excavated valleysystems, it is concluded that the main erosion predates the "Rissian" of the classical nomenclature by at least one glacial cycle. A comparison in landscape evolution of the Cover- Gravel-Area in eastern Switzerland…
