Antarctica the Meyer Desert Formation of the Sirius Group show that intermittent warm periods allowed "Nothofagus" shrubs to cling to the Dominion Range as late as 3–4 Ma (mid-late Pliocene). After that, the Pleistocene ice age covered the whole continent and destroyed all major plant life on it. The geological study of Antarctica has been greatly hindered by nearly all of the continent being permanently covered with a thick layer of ice. However, new techniques such as remote sensing, ground-penetrating radar and satellite imagery have begun to reveal the structures beneath the ice. Geologically, West Antarctica closely resembles the Andes mountain
