As you look at the majestic Crater Lake, located in south-central Oregon, United States, it is hard to imagine that thousands of years ago this place was one giant crater with scorching hot lava spilling over the sides. Those were the times of turmoil. Now, however, this place is the essence of tranquility. The lake that was formed, after the volcano died down, is amazingly clear due to the fact that the water isn’t moving at all. No rivers go in or out of the Crater Lake, and the water lost through evaporation is compensated by the rain and snowfall. This lake is also frighteningly deep – 1,943 feet (592 m) at its deepest point – making it the deepest lake in the United States. If you love nature and if you ever come to Oregon, this is truly a sight to behold.
