Electrical resistivity results at a depth of 50 cm in the area of Mound G, Toltec Mounds, AR. Mound G was leveled during the 19th century; the sharp division in contrast about 20 m inside the left figure may indicate the edge of the roughly 50 cm thickness of Mound G material, which mutes the contrast in the eastern 4/5 of the image. A variance-balancing filter evens the contrast (right) indicating substantial structure, with a number of radiating lines and arcing features, undoubtedly cultural, but currently of unknown origin.
