CRATER LAKE

The lake is 1,943 feet (592 m) deep at its deepest point, which makes it the deepest lake in the United States, the second deepest in North America and the ninth deepest in the world.

The caldera rim ranges in elevation from 7,000 to 8,000 feet (2,100 to 2,400 m). The United States Geological Survey benchmarked elevation of the lake surface itself is 6,178 feet (1,883 m). This National Park encompasses 183,225 acres. Crater Lake has no streams flowing into or out of it. All water that enters the lake is eventually lost from evaporation or subsurface seepage. The lake's water commonly has a striking blue hue, and the lake is re-filled entirely from direct precipitation in the form of snow and rain.

 There is not much that I can add to the above except that it's raw beauty is memorable.
