More of the worldâs lakes were formed by glaciers than by any other method. During the Ice Age, much of the Northern Hemisphere was covered with great glaciers that cut or enlarged depressions in the earth which later filled with water. These are called glacial lakes.
Centuries of rain and snow filled the caldera creating Crater Lake. With a depth of 1932 feet (589 meters), Crater Lake is the deepest lake in the United States and the seventh deepest lake in the world. Collapse calderas form when a large magma chamber is emptied by a volcanic eruption or by subsurface magma movement. The unsupported rock that forms the roof of the magma chamber then collapses to form a large crater. Crater Lake and many other calderas are thought to have formed by this process.
