“…and Picea-cones must have transported in by storms and floods, suggesting single trees or small groups of trees on surrounding higher areas. The palaeobotanical investigations by Drescher-Schneider et al (2007) reveal open woodland as found today at the transition from boreal forests to tundra in northern Europe or Siberia. The palaeoclimate corresponds to the situation near the tree line in the Alps and Jura mountains of today, with warm summer and cold winter with heavy snowfall (DrescherSchneider et al, 2007).…”

“…The 1 m thick mammoth peat displays different pollen associations partly dominated by Picea (Drescher- Schneider et al, 2007). Since the available radiocarbon dating (AMS) results of bone and plant material from 1890 and 1987 varied between 33,000 and 42,000 14 C yr BP (see above, Schlu¨chter, 1994), a new effort was made.…”

“…In the lower part of the peat the amount of tree pollen is very low, interpreted to indicate unfavourable conditions for tree growth on the surrounding slopes (Drescher-Schneider et al, 2007). During the following period climate improved and the valley was partly covered by open mixed forest of Picea, Betula and Larix characterised as forested tundra (Fig.…”

In 1890 more than 100 bones, molar teeth and tusks of at least seven different individuals of mammoths, including a very young calf, were found in a peat horizon at the base of a gravel pit at the village of Niederweningen, 20 km northwest of Zu¨rich. Further fragmentary fossils have been identified as remains of woolly rhino, wild horse, bison, wolf, lemming, vole, frog and bird. In 2003 and 2004 new fossils and good sections of the peat horizon were studied in large construction pits located close to the old Niederweningen mammoth site. The highlight was a well-preserved articulated mammoth skeleton with an estimated height of about 3.50 m. New 14 C-AMS dating confirm that bones and teeth of mammoth, peat and wood found in association with mammoth, have an age of about 45 ka BP. Luminescence dating of one section provides time control with ages of 70-80 ka for the sediments below the peat and 40 ka above the peat. First studies on pollen, seeds, wood and beetle allow the reconstruction of environment and climate during this time interval in the middle part of the last glacial cycle (Middle Wu¨rmian). r

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.
