There are glaciers and there are glaciers.

I've seen many of them around the world.

First of all, there are those of Antarctica, the largest ones in the world. Untouched for millennia, this is earth as it was at the very beginning. Antarctica is and will always be my favorite continent. I had the privilege to be one of the rare humans to cross part of it on my journey to the South Pole.

Next, there are poor glaciers from the European Alps, shrinking and shrinking. The ones I prefer are those of the Mont Blanc Massif. A ski descent of the Vallée Blanche, near Chamonix is a spectacle of rare beauty.

Then, there are those in Alaska, very cold and dangerous. I made myself the unpleasant experience when I fell into a crevasse on the Kahiltnaa glacier; fortunately I was roped up, and my climbing partners rescued me.

And then there are of course those of the Himalayan giants, especially the dreaded men devouring Khumbu icefall, on the south side of Everest. Every year it demands its toll in human lives. A few years ago, on my Everest attempt, I crossed it eight times, always in fear of crushing ice blocks. This glacier is moving so fast, that each time the path was different. I almost got killed by a falling block on my first passage.

Finally there is the Perito Moreno. It holds a special place in the family of glaciers. Although this is not the greatest one, it is huge. Its front is five kilometers wide. Surely you all have seen spectacular videos of huge ice towers thundering into the lake where its 30 km journey ends. These videos are often used to document global warming, which is actually a wrong pick. Indeed, the Perito Moreno is one of the few glaciers that do not shrink, on the contrary. It is doing great and even tends to grow.
But what makes Perito Moreno a rare beauty, is the fact that it ends its journey in a lake, unlike most other glaciers that slowly get covered with dust, stones and rocks, change from white to a dirty gray, to finally sadly disappear under the rubble.

The front of Perito Moreno, advances majestically with its 50 meters high white and blue ice towers (150 meters by counting the submerged part), before crushing, and finally floating away as icebergs.
