Capacitively coupled average resistivity of the Interstate and Tri-State Canals within Sioux and Scotts Bluff Counties in western Nebraska and Goshen County in eastern Wyoming

The U.S. Geological Survey, in cooperation with the North Platte Natural Resources District, used two surface geophysical techniques, capacitively coupled and direct-current continuous resistivity profiling, to map near-surface lithologies beneath the Interstate and Tri-State Canals in the spring and summer of 2004. This coverage represents the average electrical resistivity of sediments within the upper 8 meters below selected parts of the Interstate and Tri-State Canals within Sioux and Scotts Bluff Counties in western Nebraska and Goshen County in eastern Wyoming.
