| This photo released by Centro de Estudios Cientificos, shows the Cachet lake partially dried, in Aysen, southern Chile, Monday, April 7, 2008. The lake was dried up during three days (April 6-8) after the melting of neighboring Colonia glacier filled the lake and increased pressure on the ice sheet. The water bored a 5-mile tunnel through the glacier and finally emptied into the Baker River on April 6, according to glacier scientist Gino Cassasa. The lake was nearly full again by late Wednesday, Cassasa said. (AP Photo/Centro de Estudios Cientficos) |
