21st Century Methods for a 19th Century World: GIS, Geophysical Survey, and Geoarchaeology in Washington, D.C.
Author(s): Charde Reid
New and non-traditional techniques such as the geographic information system (GIS), geophysical survey, and geoarchaeology show great promise for investigating changing landscapes and urban deposition patterns. The Washington, D.C. Historic Preservation Office has begun implementing these non-invasive techniques as part of most Phase I investigations, especially in highly-developed areas. They are a cost-effective, efficient, and fast ways to identify areas of fill, buried stream channels, long-forgotten burials, lost Civil War-era defenses, and made land. These techniques are also used to identify truncated soil columns and other markers of ground disturbance. This paper describes each of these methods, and explains how they can be used in tandem. Examples of successes, challenges, and lessons learned along the way will be summarized.
