A SMALL LAKE ON TOP OF THE YANERT GLACIER CAUSED BUY THE MELTWATER. THESE SMALL LAKES ARE A BEAUTIFUL COLOR. THE WATER IS NOT BLUE IT'S CLEAR, THE COLOR COMES FROM COMPRESSED ICE. AS ALL OF THE ATMOSPHERE IS COMPRESSED OUT OF THE ICE, THE ICE ABSORBES EVERY COLOR IN THE SPECTRUM EXCEPT FOR THE WAVELENGTH OF BLUE. IT'S ACTUALLY THE LACK OF NITROGEN WHICH CAUSES THE WAVELENGTH OF BLUE TO BE REFLECTED BACK OUT.
