Electrical resistivity studies of subsurface conditions near Antigo, Wisconsin
H. Cecil Spicer
1952, Circular 181
Resistivity measurements are reported for the glaciated area near Antigo, Wis., to locate buried sand and gravel deposits in the glacial drift, which might be developed as aquifers, and to determine depths to the pre-Cambrian bedrock. The results of the resistivity study are presented both as cross sections and as...
