El Calafate is on the middle of the south shore of Lago Argentino. It is the largest lake in Patagonia and is fed by Perito Moreno Glacier - the White Giant on the west shore of the lake only 80 km away. The Parque Nacional Los Glaciares contains many glaciers but Perito Moreno is the most notable and accessable. It moves 7 feet per day so there is a lot of calving off the 200 foot wall which meets the lake. All of the Perlan team made time to visit this glacier.
