I never imagined it could be fascinating to watch a gletscher for hours. I was convinced by Perito Moreno.
Second, as the glacier advances every year, periodically the huge ice mass reaches the other side of the lake. When this happens, the natural water flow is blocked, and when the ice mass is strong enough it is able to sustain the pressure exerted by the water in the lake upstream. This has the effect that the water coming down from the Andes mountains cannot continue its flow down to the Atlantic, and instead the level of the water in the lake rises. This process continues until, the pressure of the increasing volume of water becoming too high eventually, the ice dam starts to crack, breaks into pieces and is almost entirely washed away, sending huge icebergs downstream. This process takes around 24 hours. This is a natural happening, and unique in the world. The last time it occurred (1988), it attracted people and TV teams from all over the world to watch in wonder this truly spectacular sight.
