Los Glaciares National Park, Argentina

A couple looks at the Perito Moreno Glacier as it decends into the Argentino Lake from an observatory in the Los Glaciares National Park on the Patagonia region of Southern Argentina on May 17, 2003. The front of the glacier is more than 4 km (2,5 miles) long and is more than 60 meters (200 feet) high.
