The high elevation and rugged relief (>3 km) of the Gamburtsev Subglacial Mountains (GSM) have long been considered enigmatic. Orogenesis normally occurs near plate boundaries, not cratonic interiors, and largeâ€scale tectonic activity last occurred in East Antarctica during the Panâ€African (480...
