“…In Austria, the Pasterze Glacier was limited in extent during the early Holocene, and was smaller than present for an extended period between 8100 and 6900 BP (Nicolussi and Patzelt, 2000). Further west, evidence for a later and more pronounced midHolocene warming is supported by Zoller et al (1998) and Haas et al (1998), who found tree lines were highest in Switzerland around 6000 BP. Less well-dated studies have also identified maximum timberline altitudes in the Alps between 9000 and 4700 BP (Tinner et al, 1996) and 8700 and 5000 BP (Wick and Tinner, 1997).…”

“…This time period roughly corresponds to the 'Palü ' cold event that was identified in the Central Alps based on pollen and lithological data in bog sediments (Zoller et al, 1998). Nevertheless, whether all the similar 'intermediate moraines' found between the LIA and Egesen moraines were deposited during the Preboreal oscillation remains an open question.…”

Chronological data for glacier advances in the European Alps between the Last Interglacial (Eemian) and the Holocene are summarised (115 to 11 ka). During this time glaciers were most extensive, extending tens of kilometres out onto the forelands, between 30 and 18 ka, that is, synchronous with the global ice volume maximum of Marine Isotope Stage (MIS) 2. Evidence for ice expanding to just past the mountain front for an earlier major glacier advance comes from Swiss sites, where advances have been luminescence dated to MIS 5d (100 ka) and MIS 4 (70 ka). Up to now no such evidence has been found in the Eastern Alps. By 18 ka, more than 80% of the Late Wü rmian ice volume had gone. Subsequently glaciers readvanced, reaching into the upper reaches of the main valleys during the Lateglacial Gschnitz stadial, which likely occurred around 17 ka, with final moraine stabilisation no later than 15.4 ka. The link of the Egesen stadial with the Younger Dryas climate deterioration is supported by exposure ages from four sites as well as minimum-limiting radiocarbon dates from bogs within former glacier tongue areas. Key questions on the spatial and temporal variability of ice extents throughout the last glacial cycle have yet to be answered.

“…This indicates that early Holocene climate perturbations were not limited to the '8.2 ka event' as, at several sites, the amplitude signal of the $9.2 ka (timing according to NGRIP, Rasmussen et al, 2006) exceeds that of the 8.2 ka event (e.g. Misox cold phase displayed in pollen records in the Central Alps, Zoller et al, 1998). At $9.2 ka a reduction in the North Atlantic deep water formation and thus weakening of the thermohaline circulation (Oppo et al, 2003) has been proposed to be caused by a meltwater pulse (Axford et al, 2009).…”

The Alps play a pivotal role for glacier and climate reconstructions within Europe. Detailed glacial chronologies provide important insights into mechanisms of glaciation and climate change. We present 26 10 Be exposure dates of glacially transported boulders situated on moraines and ice-moulded bedrock samples at the Belalp cirque and the Great Aletsch valley, Switzerland. Weighted mean ages of $10.9, 11.1, 11.0 and 9.6 ka for the Belalp, on up to six individual moraine ridges, constrain these moraines to the Egesen, Kartell and Schams stadials during Lateglacial to early Holocene times. The weighted mean age of $12.5 ka for the right-lateral moraine of the Great Aletsch correlates with the Egesen stadial related to the Younger Dryas cooling. These data indicate that during the early Holocene between $11.7 and $9.2 ka, glaciers in the Swiss Alps seem to have been significantly affected by cold climatic conditions initiated during the Younger Dryas and the Preboreal Oscillation. These conditions resulted in glacier margin oscillations relating to climatic fluctuations during the second phase of the Younger Dryas -and continuing into Boreal times -as supported by correlation of the innermost moraine of the Belalp Cirque to the Schams (early) Holocene stage.
