Archaeo-Physics, LLC is a consulting firm specializing in subsurface imaging of archaeological sites. We perform geophysical surveys to produce high-resolution maps of archaeological features, artifacts, and other patterning.
We use a variety of geophysical survey technologies, including magnetometry, electrical resistance, ground penetrating radar, electromagnetic conductivity, magnetic susceptibility, and LiDAR data processing and analysis. Subsurface mapping can guide excavation, reducing costs and maximizing the recovery of useful data. Because geophysical survey is non-invasive, it is an important tool for research and preservation on culturally sensitive or protected sites. In either case, geophysical methods can map patterning that may not be apparent in excavation on a site-wide scale and without disturbance.
Our staff has extensive experience performing geophysical surveys of archaeological sites in all regions of the United States and many locations throughout the world. In addition to serving as consultants to professional archaeologists, Archaeo-Physics maintains a strong commitment to education. Our staff engages in instruction and survey at field schools and public archaeology projects. We strive to disseminate the results of our work through publication, and online and public presentations.

Featured case study: LiDAR imaging of Fort Juelson
Fort Juelson is a Black Hills war era defensive earthwork located in Tordenskjold Township, Otter Tail County, Minnesota. Archaeo-Physics is conducting a two-phase non-invasive assessment of the site. Phase I involved LiDAR imaging of the hilltop. LiDAR is capable of detecting archaeological phenomena that have some topographic surface expression. Phase II will involve sub-surface imaging of buried archaeological resources. Sub-surface imaging methods will include magnetic field gradient, electrical resistance, and GPR. Data gained during the non-invasive investigation will be used to help develop an archaeological research design and to guide limited test excavations during a public archaeology program at the site. Sub-surface imaging results will be added to this site during the summer of 2012 as they become available. more >>
