They go out looking for artifacts; he goes out looking for soils.Excavations in 2003 at the Claussen site along Mill Creek in northeast Kansas revealed at least three archeaological horizons.Data evaluation included "wiggle matching" of different sets of tree rings.The results suggest that salt mining in the Hallstatt region took place in the 14th-13th century BC, well before the so-called Hallstatt period.Rolfe Mandel, shown below inspecting mussel shells in an ancient campsite buried 30 feet deep, now awaits radiocarbon dates for the lower two horizons.Images courtesy of John Charlton, Kansas Geological Survey.It could be something as simple as a run away script or learning how to better use E-utilities, for more efficient work such that your work does not impact the ability of other researchers to also use our site.To restore access and understand how to better interact with our site to avoid this in the future, please have your system administrator contact [email protected]

[Images: A New Face for Ötzi the Iceman Mummy]It appears the body was laid to rest on its left side in a flexed position and with a hammerstone (stone used as a hammer) across the forearm.Perhaps the only way to fully understand early humans is to understand their ancient environments.That simple concept underlies the field of geoarchaeology — the application of the earth sciences to archaeological studies.The measurement of the remaining proportion of 14C in organic matter thus gives an estimate of its age (a raw radiocarbon age).However, over time there are small fluctuations in the ratio of 14C to 12C in the atmosphere, fluctuations that have been noted in natural records of the past, such as sequences of tree rings and cave deposits.
