I love to visit places where I can still sense the wild and rugged nature of our planet. Perhaps this is why I am so drawn to mountains. Viedma Glacier crystallizes from the Patagonian Ice Cap atop the Andes Mountains in southern Argentina. It is just one fingertip from this, the world's fourth largest chunk of ice, after Antarctica, Greenland, and the Himalayas. The photo shows the glacier terminus in the lake of the same name. The various shades of rock, sky, and water highlight the myriad hues of psychedelic blue and green ice in this great glacial "toe".
