The source of the Transantarctic Mountains’ high elevation has remained unclear. Here, the authors present data from a 550 km long magnetotelluric geophysical transect showing that uplift is likely to be mechanical via cantilevered flexure along a master boundary fault and not upper mantle or lower crustal thermal mechanisms.
