65 km northwest of Shiraz under a huge mountain lies a lush spring in front of the 3600 m Ronj mount outskirts. The locals consider this 2200 m high spring as sacred and its seeping qualitative water is utilized for bottled mineral water. In the vicinity of this sacred spring a 40000 m wide fresh water lake is located which is fed by some springs inflow. The average depth of this lake is 3 to 11 meters, yet the exact central depth has not been estimated. In winter this lake freezes completely solid and creates a breathtaking vista.
