Years ago while living in Buenos Aires, I decided to take my first trip alone, to the edge of Argentina, down in Patagonia. Running along the Chile-Argentina border, Perito Moreno is one of three Patagonian glaciers that is not retreating. It covers almost 100 square miles! I still remember the moment, out of the bus window, that Perito Moreno first came into view. The enormity of it blew me away. The following day I had the chance to actually walk on the glacier. Clamping on my crampons, I recall the flurry of butterflies in my stomach, reaching up to my throat. I remember the crunch of the snow beneath my feet. As we walked over the first mound of ice, I felt like I was on top of the world, or perhaps, on top of the moon. The crevices of melting ice created a blue so striking I don't think it can be matched; like a fairy tale image of nature's perfections. I'll never forget that afternoon of hiking, looking down on the shores of Patagonia beneath me and the overwhelming beauty of Perito Moreno in front of me.
