Magnetic surveys locate Late Bronze Age corrals
A new type of livestock enclosure from the Late Bronze Age has been discovered. Stone walls outline a pair of circular or oval areas that may be up to 50 m in diameter. The stone walls are invisible at the surface; they were discovered in north‐western Crimea and only with the aid of remote sensing and geophysical surveys. In the period 2007–2020, over two dozen of these structures were found; none has ever been noted before. The locations of the…
Creating a community of prospection practitioners
An annual series of lectures and field exercises has provided training in the archaeological application of geophysical, aerial and other remote sensing methods; this week‐long workshop has been coordinated by the US National Park Service (NPS) since 1991. Volunteer instructors have trained nearly 900 attendees at a variety of prehistoric, protohistoric, and historic sites across the United States. This NPS workshop is the longest‐standing traini…
The Discovery of an Ancient Greek Vineyard
Relatively few geophysical surveys have shown how buried traces of agricultural fields can be revealed. An ancient Greek vineyard on the Crimean peninsula was first suggested in a satellite photograph; however, it was discovered only with a magnetic survey. This survey found a 5.7‐ha field that is crossed by about 80 buried stone walls that are parallel and spaced by 2.6 m; this pattern is found only in the vineyard. Later excavations revealed un…
The Measurement and Analysis of Depth in Archaeological Geophysics
Information on depth may be gained through the analysis of geophysical maps, by utilizing soundings, pseudosections, or time‐slices, or via the application of downhole measurements. Various methods and techniques were compared at the Biesterfeldt site, a proto‐historic earth‐lodge village in the Northern Plains, USA. Both traditional and more experimental approaches were used, including ground‐penetrating radar time slices and overlay analyses, a…
Geophysical Exploration for Buried Buildings
Geophysical exploration of Guajará, a prehistoric earth mound in Brazil
An interdisciplinary team studied Guajará, a prehistoric artificial mound in the Brazilian Amazon. The geophysical surveys and excavations were interactive;this interaction furnished more information than either geophysics or excavation alone could have provided. While seven different geophysical methods were applied, the magnetic survey reported here was particularly valuable. A detailed interpretation of this survey quantified the magnetic mate…
Geophysical indicators of culturally emplaced soils and sediments
Archaeologists dealing with earthen forms must distinguish those constructed by humans from those with a natural origin. Geophysical techniques can help identify culturally loaded soils and sediments. We suggest that intrinsic changes in geophysical properties, due to cultural loading, can serve as fingerprints in determining whether a mound or other earthen form is natural or culturally constructed. Culturally emplaced soils might be identified …
An early geophysical survey at Williamsburg, USA
The first known geophysical survey for an archaeological application on the American continents was carried out in 1938. An equipotential map was measured at the historic site of Colonial Williamsburg, in the USA. This type of survey is similar to a resistivity survey, and it located a high resistivity feature within a churchyard. The survey was designed to locate a stone vault buried below that churchyard; however, the geophysical anomaly was ca…
The magnetic anomaly of a brick foundation
This experiment was done at the foundation of a chapel that was constructed about 300 years ago at St Mary's City, Maryland, in the USA. The magnetic anomaly of this foundation is irregular and lumpy. The magnetic map does not show a uniform band with a high magnetic field along the line of the foundation; instead, it shows a series of high readings spaced unevenly near the foundation. This irregularity is caused by the addition and subtraction o…

Electromagnetics for Mapping Buried Earth Features
Electromagnetic surveys are a fast method of locating and mapping some large earth features such as leveled mounds and refilled ditches. They can be a substitute for resistivity surveys and are particularly suitable where the surface soil is dry, hard, or rocky, or where the vegetation is moderately dense.As in all geophysical techniques, it is necessary that the features to be located are sufficiently different from the surrounding terrain. Resu…
