Notes
Magnetotelluric soundings along a profile extending from the Raft River geothermal area in southern Idaho in Yellowstone National Park in Wyoming reveal a highly anomalous crustal structure involving a conductive zone at depths that range from 18 km in the central part of the eastern Snake River Plain to 7 km beneath the Raft River thermal area and as little as 5 km in Yellowstone. Resistivities in this conductive zone are less than 10 ohm-m and at some sites than 1 ohm-m.
