Book excerpt: Earlypeoples migrating to the Americas via the coastal migration route would havetravelled through southeast Alaska during periods with lower sea levels. Theresidues of where they lived, hunted and gathered are on the now submergedcontinental shelf of southeast Alaska. A GIS model, two years of marinegeophysical survey (including side scan sonar, sub-bottom profiling andmultibeam sonar) and minimal subsurface testing have allowed the author torefine the methods for locating submerged archaeological sites buried on thecontinental shelf. The environment is reconstructed in 500-year intervals, andthese intervals are used to create a predictive model for each time periodusing inductive and deductive methods. The final model combines the intervalmodels for a final prediction of probable archaeological sites within theregion.
