Perito Moreno Glacier

 

The enormous Perito Moreno glacier rests here, rising nearly 200 feet above the Iceberg Channel, spanning three miles across, and reaching back 22 miles through the Andes to Lago Argentino. Regarded as one of the world's natural wonders, Perito Moreno advances and collapses in a constant cycle that repeats every four years. Throughout the day, huge blocks of ice break away from the glacier and crash into the lake with a resounding thunder, creating icebergs that float downstream. Perito Moreno can be enjoyed with a boat sightseeing tour or simply walking on comfortable wooden walkways (pasarelas) placed just in front of it.The area was declared a World Heritage Site in 1981 by the United Nations Educational, Scientific, and Cultural Organization (UNESCO).
