Waterfall Lake

A large freshwater lake at the foothills of a glacial mountain. Its waters are blue and crystal-clear, and the floor is lined with hard white stone that also extends out of the lake and onto the shore to form a platform. There is a fast-flowing stream also lined with smooth white stone flowing from the mountain to the lake, creating a waterfall effect. There is a small stream that flows from the lake to form a river that flows out a ways. There is said to be a hole in the stone, leading to a tunnel which leads to a small hidden cavern lit with luminecent crystals on the ceiling, but no one had found it yet that we know of.
