malformalady:A rare natural phenomenon turns one of Austria’s most beautiful hiking trails into a 10 meter-deep lake, for half the year. Located at the foot of the Hochschwab Mountains, in Tragoess, Styria. Green Lake(Grüner See) begins to appear as temperatures rise in the summer months, the snow and ice covering the mountaintops melt, and the water pours down, filling the basin below with crystal-clear water. -- source link
