Archaeological investigations using geophysics at Chimney Rock Great House, Colorado

In this talk, we present results from a geophysical investigation at the Chimney Rock Great House using magnetics, electromagnetics, and DC resistivity. Our data is focused on a grid southwest of the Great House, where we use geophysics to detect potential buried walls. These walls may be covered by 1 to 3 m of fill as a result of nearby excavations in the 1920s, and should be approximately 0.5 m thick. Using geophysics, we were able to identify several potential targets in the multiple datasets, which are consistent with sketches from earlier archaeological digs. Through our investigations, we have likewise gained a better understanding of the geophysical responses of buried walls at Chimney Rock.
