Perito Moreno is one of the most beautiful glaciers I have seen. It is located in the Los Glaciales National Park in Santa Cruz province, Argentina. It's 30km long and a part of an ice field that is the world's third largest reserve of sweet water. The day I came there were clouds rolling over it reflecting in many hues the deep blue color of the densely packed ice of the glacier.
