article imageGlacier Melts And Empties lake

By Gar Swaffar     Apr 11, 2008 in Environment
Colonia glacier in Chile feeds Cachet Lake, which recently filled and then dried up. The lake dried up after emptying itself rapidly into Baker River in the Southern region of Chile.
Proponents of Global Warming point to the recent emptying of at least two glacial melt lakes in Chile as further inescapable proof of the reality of Global Warming and it's effect on the environment. Cachet lake in the South of Chile is one example of a Glacial melt lake which has recently been filled to overflowing by glacial melt. The excess water being held in the lake appears to place more pressure on the glacier and in some cases melting a hole or tunnel into the glacier.
Such was the case with Colonia Glacier, the tunnel which was bored by the excess melt in an extremely warm winter season in the Southern Hemisphere was five miles (8 km) long. That in turn allowed the water to escape precipitiously to the Baker River which apparently ran backwards for some time until the rush of water had eased. The lake emptied completely and has since begun to refill.
Glacier scientist Gino Casassa of the Center for Scientific Studies in Chile is studying the occurrence.
