The length from north to south is 360 km, the width is from 40 to 90 km. The area is about 12,000 km². The prevailing heights are 1500 m. Nunataki (rocky peaks protruding above the surface of the glacier) and mountains rise among the ice. The highest point is Mount Bertrand (3270 m). The height of the firn line decreases from 1200 m in the north to 650 m in the south. At the level of the glacial plateau, 7000-8000 mm of precipitation falls annually. The latitudinal iceless depression against Lake Lago Argentino divides the glacial plateau into two parts - the vast northern and the small southern.
The output glaciers flow down from the plateau, many on the western side end in the fjords , on the eastern side - in the lakes ( San Martin , Viedma , Lago Argentino ). The largest outgoing glaciers: Greve , Bruggen , Guillardi , Amalia (flow west); Jorge Mount (North); O'Higgins , Viedma , Uppsala , Perito Moreno , Gray , Tyndall (to the east).
