The Sublime Beauty of Patagonia’s Perito Moreno Glacier

Dark clouds hang dramatically in the sky, contrasting with soaring white cliffs streaked with deep blue and rising high above a turquoise lake. The smell of ice hangs in the air, as does the creaking, rolling sound of ice on the move. Occasionally that sound rises to a crashing boom as huge chunks break off and hit the lake’s surface.

This is Argentina’s Perito Moreno glacier, remarkable both because it is the world’s third largest source of freshwater, and because — despite global warming — it is still growing. One of 48 glaciers fed by the Southern Patagonian Ice Field, Perito Moreno is currently about 197 feet (60 m) high and 3 miles (5 km) wide.
