This photo does not do justice to witnessing the event of breaking off and collapsing glacier chunk. At first, there is a loud, empty-like cracking sound which alerts you that something is about to happen. This is followed by a sight of a collapsing chunk of the wall of ice into the water. The collapse is accompanied by a thunder-like sound of the collapsing ice as well as the sound of waves made by the displaced water. Then, there is a farily long-lasting slushing sound of the small icebers bumping into each other as they come to rest in the water. The event exposes the most beautiful blue ice in the glacier wall. Although the crackling and small break offs are fairly common on Perito Moreno Glacier, it is not easy to witness a sizeable event as this one. We got lucky to witness the event portrayed here, but then unsuccessfully waited and waited for another one.
