Perito Moreno Glacier, Patagonia, Argentina
I looked up Glacier in Wikipedia and it says "A glacier is a perennial mass of ice which moves over land. A glacier forms in locations where the mass accumulation of snow and ice exceeds ablation over many years... Glacier ice is the largest reservoir of fresh water on Earth, and is second only to oceans as the largest reservoir of total water"
Perito Moreno Glacier in Patagonia,Argentina is one of the few Patagonian glaciers that is not retreating. It's a couple of hours from El Calafate, Patagonia and I took a tour to go and visit it. The day I chose the visit it, we had pretty bad weather condition - it snowed very hard the entire way there and while I was there trekking around the park to see the Glacier from different views, we had a mini snow storm. I was not geared properly and i froze myself up. Was among the coldest I ever felt while there.
The glacier is a spectacular sight and it was amazing to see it up close and to gear the thundering noise of the ruptures of ice from the glaciers. It happens al day long when huge pieces of ice from the glacier break off and fall in the adjoining Lake.
There are tours to actually go and trek over the glaciers, but in the time I went, the weather did not permit such trekking.
