Blue Icebergs?

In South America????

Off the southern coast of Chile these mammoth freaks of nature can be found, if you can believe it.  A cruise here would be fascinating.  It is said that these large chunks of ice have broken off from a glacier near the Northern Patagonia fields, about 3,000 miles from the South Pole, and can be viewed from a national park in the lower tip of Chile.  There is no supernatural mystery to the beautiful color of this ice.  The blue glow results from a long cycle (for centuries) of freezing and melting that makes the frozen snow dense and airless.  Scientifically speaking: “Molecules of compacted ice crystal absorb red light, which has a long wavelength, and reflect only the shorter wavelength, blue.”  Unfortunately, we have a limited time in viewing this surreal phenomena of nature.  The recent climate changes have doubled the melting rate.  By 2030 these babies will be nothing more than tiny ice cubes that we’ll be able to float in a drinking glass.
