Of tarns and towers

There's no shortage of glaciers in this national park named for them in the Patagonia region of Argentina. The treasures of Los Glaciares National Park extend beyond the ice, with some of the world's richest fossil beds, highest mountains, and biggest glacier-fed lakes found anywhere. Here at the tarn called Laguna Torre we can see the east face of the Cerro Torre group and its spiky summits—just a tiny slice of the world's longest continental range, the Andes.
