The Perito Moreno Glacier slowly makes its way down to the lower ground of Argentino Lake. At its end the Perito Moreno Glacier has an average thickness of 170m (558ft) with 74m (240ft) visible above the water line of the lake. With over 250 km2 (97 sq mi) of ice the glacier spans 30 km (19 mi) in length and a width of 5km at its terminus. Since 1968 rupturing ice has taken the lives of 32 people who were hit by flying ice. One of 48 glaciers that form part of the Southern Patagonian Ice Field, the high altitude field has a total area of 12,363 km2 (4,773 sq mi) of ice.
