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.The following geoarchaeology vignettes show that geological stories are inseparable from the human ones: Sea level can rise causing populations to migrate. Climate can alter the soil and shift the course of a culture. Together, geologists and archaeologists can unravel our past and better plan for and understand our future.For 25 years, geologist Rolfe Mandel has been studying early Americans.These include the main stable isotope (12C) and an unstable isotope (14C).Through photosynthesis, plants absorb both forms from carbon dioxide in the atmosphere.The pretty face of a woman who lived more than 13,000 years ago in what is now Thailand, and is considered a likely descendant of the first humans to populate Southeast Asia, is seeing the light of day.Scientists have created a digital reconstuction of the woman’s face based on skeletal remains found in 2002 in the Tham Lod rock shelter in northwest Thailand.
