Description
It's hard to grasp the scale of this shot at first glance, but as the creeping clouds probably tipped you off, we're seeing something much larger than a half-frozen pond. To give you just an idea, the edges of that ice sheet rise 73 metres above the surface of Argentino Lake . Sail along the whole length of the sheer ice cliff and you'll have travelled more than 3 miles. And this is just the tip of the iceberg – er, glacier . Beyond this narrow end that feeds the 500-metre-deep lake, Perito Moreno Glacier covers almost 100 square miles. Even bigger news: unlike most of Earth's glaciers, this ice giant is actually growing.
