Earlier magnetic surveys at the site were successful and we were anxious to try some new methods as well.
Geophysical studies can be complex in their application and interpretation.
However, there are a few simple principles that guide this type of investigation. First, all archaeological materials have geophysical properties that are an important part of the archaeological record. Second , different geophysical methods can identify different kinds of things and at different depths and resolutions. High frequency radar antennas can penetrate only forty or fifty centimeters beneath the soil but can resolve items that are inches in size. Low frequency radar, on the other hand, can penetrate ten or more meters beneath the ground but will only identify very large features that measure one or two meters across.
