The famous lake Merzbacher, situated at a height of 3300 m is named after the explorer Gottfried Merzbacher, he was the first one who wrote extensively about the Lake. Actually the Lake consists of 2 lakes, one with only water and the other one with water and big ice-bergs. Once a year, in summer, all the water of the upper lake, flows into the lower lake and make these ice-bergs swim. The water finds a way out of this big lake and flows under the North Inylchek Glacier and, nobody knows how!, into the River Inylchek. This magnificient sight of floating ice-bergs and the noise of the massive waterflood you can hear echoing in the area…
