Ahler, S. A. (Northern Arizona University (USA)). Scattered Village Site, North Dakota, USA. H. Haas, C14 in archaeology, arch.
This site is situated within the City of Mandan in North Dakota. The samples dated span the time period from 1600 to 1800 AD. This period covers locally the late phase of the Mandan and Hidatsa Indian culture and the transition to the dominant white settler culture.

Arnold (1), B. and N. Thew (2) ((1)Musée cantonal d'archéologie, Neuchâtel, CH
(2) Archaeological Service for the Canton of Neuchâtel, CH). Reconstruction of human settelments in the region of Lake Neuchâtel: the past 14,000 years, C14 in archaeology.
In the latter part of the 20th century, when it was decided to build the A5 motorway along the littoral zone of the north-eastern part of the lake, it became necessary to organise rescue excavations. Since the 1970's, the Archaeological Service for the canton of Neuchâtel has undertaken large-scale excavations at various sites in the Bay of Auvernier (1972-75), at Cortillod-Est (1981-84), at Hauterive-Champréveyres (1983-86), and at Saint-Blaise/Bains des Dames (1986-88), as well as a number of smaller interventions. Radiocarbon dating of material (mostly charcoal) recovered during the 1990s (more than 800 samples) documents constant presence of human settelments in this region for the past 14,000 years.

The 1856 discovery of the Neandertal type specimen (Neandertal 1) in western Germany marked the beginning of human paleontology and initiated the longest-standing debate in the discipline: the role of Neandertals in human evolutionary history. The analysis of sediments from the Feldhofer caves represents the first interdisciplinary analysis of Neandertal remains incorporating genetic, dating, and morphological dimensions simultaneously.

Caduff, B. and M. Seifert (Archäologischer Dienst Graubünden). Roveredo, C14 in archaeology, arch.
From the construction of a new freeway tunnel by Roveredo a big area of grasland will be covered with earth-material. Before this work the archeological service have to find out with a survey if there are archeological remains in the soil. In the year of 2002 he made 4 cuts. In them in different layers are founded concentration of charcoal without remains like potsherds, they can give a term of the origin. Thanks to nine 14C-dates, the archeological layers can be situated in the late bronze age and the iron age. Beyond that this dates authorize the service to make an excavation in a define area in the years of 2003 until 2005.

Clavadetscher, U., H. Seifert and M. Seifert (Archäologischer Dienst Graubünden). Tomils-Sogn Murezi, C14 in archaeology, arch.
Since 1994 the Archäologischer Dienst Graubünden has excavated in Tomils the structure of a church, connected with different houses, they can be part of a monastery. There is is also a cemetery. The beginning of the settlement in this area goes back to the roman period. Because the different walls have been broken and rebuild and because finds that date are very rare in churches, the development and the absolute dating of the building periods between the roman occupation and the 16th century could only be discovered through 14C. Thanks to the dates the connection between the graves  and the different building periods of the church could also be confirmed.

Fasnacht, W. (Schweizerisches Landesmuseum, Zürich). Excavations at Agia Varvara-Almyras, C14 in archaeology, arch.
Working and living at the copper Production site of Agia Varvara-Almyras were investigated during the past twelve years.

Janosa, M. and M. Seifert (Archäologischer Dienst Graubünden). Trimmis - Reformierte Kirche, C14 in archaeology, arch.
Before the building of a new rectory by the church of Trimmis the Archäologischer Dienst Graubünden had to excavate the concerned area. Founded was a very good preserved house of the period between the last iron age time and the early roman occupation. This was the first settlement of a bad known prehistoric period in the canton of Grison. Because the short time of settlement there are so few finds for datation that the time-era could be realised only through the 14C-method

Between 1984 and 1995, over 450 organic samples were collected from monuments built during the Old and Middle Kingdoms. The purpose was to establish a radiocarbon chronology with samples from secure context and collected with the careful techniques required for radiocarbon samples. This chronology is compared to the historical chronology established by reconstructing written documentation.

Mäder, A. (Kantonsarchäologie Zürich). Ausgrabungen und Auswertung der archäologischen Fundstelle in Elgg-Breiti, Kt. ZH. - Anthropologisches Institut der Universität Zürich
 C14 in archaeology, arch.
The discovery of the site Elgg-Breiti in the canton of Zurich led to archaeological excavations lasting several years from 1996 onwards. By the year 2000 approximately 160 prehistoric features had been uncovered. The extensive finds from the areas of burnt soil, graves, pits and post holes can be attributed mainly to the early Late Bronze Age and to the Late Latène period.

Rageth, J. and M. Seifert (Archäologischer Dienst Graubünden). Untervaz-Haselboden, C14 in archaeology, arch.
In the neolithic hill-village of Untervaz-Haselboden the finds are so rare, that a exacte datation was possible only through 14C-dates. With three dates the duration of the settlement could define in the period between 3300 and 3000 BC. The determination of a short tree ring curve however was in this case not successful with the 14C-method.

Ruoff, U., J. Wiget and B. Eberschweiler (Amt für Städtebau, Denkmalpflege und Archäologie, Seefeldstr. 317, CH-8008 Zürich). The region of the lakes of Zurich during the Neolithic and Bronze Age, C14 in archaeology and dendrochronology, arch.
The absolute dating of prehistoric lakeshore settlements was based long time mainly on the dendrochronological dating of building woods made of oak. The necessity, to develop main curves for different wood, different time periods and different small regions in the Neolithic and in the Bronze Age was already for a long time obvious: Small data sets and the one-sided adjustment on one wood always save the danger of a coincidental selection, which is to be avoided in this project.
One main point of this project is to fix dendrochronological results by series of 14C measurements by wiggle matching.

The subject of this project from the Swiss national foundation in collaboration with the siberian branch of the Russian Academy of Sciences was the building of a tree-ring mean-curve for the iron age culture, named Pazyrik, in the Altai mountains. With more then 200 logs from different burials, conserved in the permafrost soil, a 415 tree-ring curve could be realised. For the absolute dating two series of 14C-interval-samples are taken. With them the absolute dating of the Pazyrik culture, it is the first time, between 350 and 250 BC was possible.

The project deals with the early iron metallurgy in regions east of the river Rhine between the 6th century BC and the early medieval time which was settled by Celtic and Germanic tribes in those days. Main issue is the research of the socalled chaîne d’opératoire in order to evaluate the importance for the contemporary economy and society. Main interest is addressed to two core-regions in the Middle Lahn valley and in the Siegerland, the first favoured by agricultural and traffic situation. The second can be described as typical montane region that was specialized in iron mining and smelting especially in Iron Age. 14C-dating has a great importance in dating smelting and mining sites especially small amounts of charcoal found in slags or in drilling cores.

Seifert, M. (Archäologischer Dienst Graubünden). St.Moritz-Quellfassung, C14 / dendrochronology, archaeology, arch.
For the wooden construction for the fountain of St. Moritz, excavated in 1907, the absolute dating was unknown, though inside two swords, a knife and a needle from the bronze age are found. In a first step the Archäologischer Dienst Graubünden investigated the beams with the dendrochronological method. Because the absence of a mean curve from today until the 3./4. millenium in the alps, it was impossible to find the absolute dating. With a series of 14C-interval-measurements the time-era could be defined exactly, so that an absolute dating in the 15th century BC was practicable.

Seifert, M. (Archäologischer Dienst Graubünden). Waltensburg-Jörgenberg und Triesenberg-Haus Nr. 65, C14 / dendrochronology, archaeology, arch.
In the walls of the castle Jörgenberg in Waltensburg some burned beams are conserved. For a dating by dendrochronology the Archäologischer Dienst Graubünden took samples from all of them. The art historians had some`s doubts about the resulted dates in the 13th and 14th century. With 14C-intervall dates the dendrochronological terms could be confirmed. The same case was a blockhouse in the community of Triesenberg, where the dendrochronological date of the beginning of the 19th century was at variance with the date from the art historians in the 15th century. They also verify the 14C-dates the tree-ring terms.

Seifert, M. (Archäologischer Dienst Graubünden). Untervaz-Kiesgrube Herti, Dendroclimatology, C14, archaeology, arch.
In association with the building of a connected tree ring curve from today until the prehistoric time the Archaeological service started in the year of 2000 a long time project to collect samples of trees, they come out of rivers, glaciers and moor lands. The long dated objective of this project is the reconstruction of the climate in the alpine mountains of Grison for the last 10’000 years. The first sample was an oak tree, found in a depth of 30 metres in the river of Rhein. It was uncertain dated with the dendrochronology of the year 27 BC. The 14C-Datation confirms this date.

Before the building of a new garage underground at the hill-castle "Hof” in Chur, the Archäologischer Dienst Graubünden had to excavate a large area. Under archeological layers of the late roman period there was a level just with tools of flintstone. The flintstone material was so untypical and unknown that only 14C-dates could be give a term for this archeological site. With these dates at the transition from the paleolithic to the mesolithic period the oldest place of a settlement in Grison is known.

Stöllner, T. (Deutsches Bergbaumuseum, Department of Mining Archaeology, Bochum D). Siedlungs- und Wirtschaftsgeschichte des prähistorischen Dürrnberg bei Hallein. (1) Oestereichisches Forschungszentrum Dürrnberg, Wien

The project deals with economy of the prehistoric salt-works at the Dürrnberg near Salzburg with mining structures below and above the gorund as well as the economic structures in settlements. Due to salt conservation or waterlogged conditions organic material is preserved in huge quantities. Most imortant are dencrochronological investigations to estamate the chronology of mines and settlement precisly. In combination with a lot of AMS-dates wiggle-matching became possible and allowed an exact correlation with Central European standard curves. Up to now around 50 AMS-dates were conducted in Zürich covering the to main periods of salt-mining in the Iron Age and the Medieval period.

The project is organized as joint project with the general aim to explore the first steps of mining and metallurgy at the West Central Iranian plateau. Our part project is focused on ancient mines especially to understand early economic relations between ore-mining, smelting, casting and metal trade in the 4th to the 2nd millenium BC. 14C-dating is again essential for dating metallurgical installations and mines by isolating charcoal and bones in securely stratified contexts.

PECHORA is a Russian-Norwegian interdisciplinary research project aiming to reconstruct late Quaternary environments, climate change and the history of Ice Age humans in the Pechora area, northern Russia. Within this, two subprojects have used 14C dates from ETH.
Nearly 40,000 years old traces of human occupation with stone artifacts and human made marks were discovered at Mamontavaya Kurya. This is the oldest documented evidence for human presence at this high latitude (Arctic Circle).
Coring of two dead ice lakes revealed that the lakes where formed at 13 ka which is remarkable young compared to the deglaciation occurring at 80-90 ka. This implies that buried glacier ice survived in the permafrost for a period of c. 80 kyr. Cores from a third lake located outside the glaciated area cover a sequence from the late Saalian, Eemian, parts of Wechselian and Holocene. However, there seems to be several large hiatuses during the coldest periods as the LGM when the lake probably dried out.

Wiget, J. and B. Eberschweiler (Amt für Städtebau, Denkmalpflege und Archäologie, Seefeldstr. 317, CH-8008 Zürich). Rosshorn, 14C in archaeology and dendrochronology, arch.
In Switzerland indications regarding traffic routes and connections outside of prehistoric settlements are very few well-known. Therefore comes a completely special meaning to the place discovered at the north end of the Hurdener spit of land two years ago. The examined stakes from selected places, are representing remainders of the subconstruction of ways through humid areas as well as remainders of shorter or longer bridges between the two lakeshores. The main problem from this place is, that stakes from different dendrochronological phases are present, which are badly occupied. Therefore it is of large importance to fix chronologically these woods and/or main curves by 14C-analysis.

Wild, D. (Denkmalpflege und Archäologie, Amt für Städtebau der Stadt Zürich,). Archaeological investigations in the Zurich Rennweg Quartier, 14C in archaeology, arch.
The renewal of wastewater disposal lines in the old city of Zurich led to sensational discoveries for the history of Zurich. Two moats were discovered, one at Rennweg itself and a second one in the Fortunagasse and the Kuttelgasse. 14C measurements showed that these moats can be dated to the 10th /11th and 11th /12th century AD. This demonstrates that Zurich was already fortified before the 13th century AD, and thus an old dispute could be settled.

Wild, D. (Denkmalpflege und Archäologie, Amt für Städtebau der Stadt Zürich,). Archaeological investigations in the house at Schmidgasse 5, 14C in archaeology, arch.
Older settlement structures were discovered during the construction of a basement in the house at Schmidgasse 5 which could be dated by 14C measurements to the 6th /7th, 8th /10th and 11th /13th century AD. So far, the Niederdorf was considered be one of the younger parts of the city of Zurich, an opinion, which has to be revised now. It is now recognized that Zurich was a polycentric city during the early and high Middle Ages and did not develop from a single center.

Wild, D. (Denkmalpflege und Archäologie, Amt für Städtebau der Stadt Zürich,). Archaeological investigations in the Kappelergasse, 14C in archaeology, arch.
During the renewal of the wastewater disposal lines in the Kappelergasse, a predecessor of the Fröschengraben was discovered, which was the water-filled moat of the fortification of the city in the 13th century AD. This predecessor could be 14C dated to the 11th/ 12th century AD. In addition, the remains of the wall surrounding the Fraumünster abbey as well as of two earlier phases could be documented. The older phase was a trench whose infill could be dated to the 5th to 8th century AD. With one additional date, the end of the infilling in this region with coarse grained material from the river Sihl could be dated to around 1000 years BC.

Wild, D. (Denkmalpflege und Archäologie, Amt für Städtebau der Stadt Zürich,). Archaeological investigations on the Lindenhof, 14C in archaeology, arch.
Static clarifications by the Zurich Civil Engineering Office on the supporting walls of the Lindenhof, the central hill of Zurich,showed early remains of settlement from the early Celtic-Roman period and the base of Roman house from the 2nd /3rd century AD. A deep trench might be the remains of a palisade, dated to be late-Celtic to early-Roman or early to high Middle Ages. The dating of this palisade is under the way.
