Transient electromagnetic soundings were used to map the geoelectrical structure of Newberry Volcano in central Oregon. An extensive conductor was found to underlie the volcano and to have resistivities from 20 OMEGA m to 72 OMEGA m. The depth to the conductor ranges from 410 m to 870 m. Inside the caldera, low basement resistivities are the result of hot fluids. The cause of the conductor outside the caldera is not known; however, we speculate that it is due to the water table.
