Dating the iceman
We discuss in some detail the chemical pretreatment of the samples and the data evaluation.
We also present a comprehensive survey of (super 14) C dates available in the literature concerning both botanical remains from the vicinity of the Iceman and from the earliest salt mining in Hallstatt.
Answers to all Concept Mapping worksheets are provided in the Teacher. You will answer these questions on your Worksheet Link 1. Develop a list of at least 10 interview questions which the Iceman will answer.. Develop a list of at least 10 interview questions which the Iceman will answer..
The prehistoric mummified corpse - soon known worldwide as "" the Iceman - together with its unique set of artefacts provided a unique opportunity for the research of a Copper-Age culture in the European Alps. And the recent retreat of the glaciers still continues, in 1970 the glacier that revealed the mummy was part of the much greater Niederjoch-Glacier, a composite alpine glacier that descends northward in the Nieder-Valley, but only in the last 5 years this glacier lost 60-100m in length. The "Similaun" as highest peak (3.597m) with his two main glaciers, the "Similaun" in foreground, and the "Niederjoch" in background. 1970 the glaciers merged, but the glacial retreat in the last years was notable. Location (black circle) of the site of the bronze-age mummy in the Ötztaler Alps.
This has very important influence on the reconstruction of past and modern climatic and glacial development and can contribute to the actual discussion about climatic change. Simplified Holocene subdivision and glacier variations in the European Alps according to MAISCH (2000), PATZELT et al. The first half of the Holocene is characterized by a general lowstand of the glaciers. (1996): Short paper - the alpine "Iceman" and Holocene Climatic Change.
The Iceman died during a phase of glacier advance (Rotmoos II), afterwards the glaciers display minor variations approaching the year 1850 highstand.
The trim line can also recognized locally as marked weathering line that separates different oxidized reddish surfaces (the bed rock consists of Fe-rich gneiss and schist). Both the axe shaft and the long bow were found in the vicinity of the corpse and were made of yew (). I discuss broadly also general geological concepts, especially in glaciology, seismology, volcanology, palaeontology and the relationship of society and geology.
A second trim line is marked by an abrupt change in lichen diameter (from 100mm above to 40mm below) and density. The majority of wood species found with the Iceman grow in the montane regions (valley bottoms to 1.800m), although some subalpine (1.800-2.500m) and alpine (above 2.500m) conifer species are also represented.

The mummy itself was dated by radiocarbon dating to 4.500 -30 and 4.580 -30yr Before Present, which corresponds to a calibrated age of 5.300-5.050yr B. The relatively sudden burial of the corpse in a more or less permanent snow and ice cover indicates a significant climatic change that induced glacier expansion at the beginning of the Neoglaciation in the second half of the Holocene. All that is similar to the present-day conditions in the woodlands found on the slopes and in gorges in the lower Schnalstal and Vinschgau in South Tyrol, where it is assumed he lived.
