Perito Moreno Glacier

---

Today I caught a bus from Puerto Natales, Chile, across the border to the Argentine town of El Calafate onto the famous Perito Moreno Glacier. The location of the glacier make it remarkably easy to see, so at any given time there are hundreds of people wandering around the 7 different levels of viewing platforms. It´s incredibly active, so for the 3 hours I was there watching the glacier, I regularly witnessed building-sized chunks of ice calve off the glacier´s 150 ft face into the water of Lago Argentino below. It periodically advances, touching the mainland, separating the lake into two. This causes one side of the lake to fill with water, until the pressure is sufficient to break the ´dam´caused by the glacier, creating an explosion of ice and water as the ice dam fails. Truly amazing!
