Two TEM soundings over the Manzanar low resistivity zone
Below a thin well conducting oberburden lies the basement with resistivities ≥ 1000 Ω*m. At depths of ~120m (left) and ~260m (right) the resistivity decreases strongly indicating the hot water aquifer. The surface of it remains ± at the same level. The different depths are due to the different altitudes of the points.
