Triglav Lakes Valley

The Triglav Lakes Valley is a rocky hanging valley in the Julian Alps in Slovenia, below the sheer sides of Mount Tičarica and Mount Zelnarica southwest of Triglav. The valley is also called the Seven Lakes Valley, although there are ten and not seven lakes in the valley. It is above the tree line and is geologically alpine karst; therefore it has also been termed the Sea of Stone Valley.
