(GSM)?<\/h2>\n<ul>\n<li>The\u00a0<strong>Gamburtsev Subglacial Mountains<\/strong>\u00a0are a\u00a0<strong>completely buried mountain range<\/strong>\u00a0beneath the\u00a0<strong>East Antarctic Ice

buried<\/strong>, concealed under several kilometres of ice.<\/li>\n<li>Typically,\u00a0<strong>mountains form at tectonic plate boundaries<\/strong>\u00a0due to\u00a0<strong>collision or subduction<\/strong>, but\u00a0<strong>East Antarctica has remained tectonically stable<\/strong>\u00a0for hundreds of millions of years.<\/li>\n<li>The existence of such a massive mountain
