Slice through the THO-MT-2021 resistivity model at 30 km depth. White dashed lines mark interpreted geophysical boundaries. Diffuse black line and red ellipses mark the North American Central Plains conductor and previously imaged conductors, respectively. White squares indicate packages of west- (W) and east- (E) dipping seismic reflectors. See Bedrosian and Finn (2021) for details.
