Crater Lake actually started as a mountain, Mount Mazama. A volcanic eruption roughly 7,700 years ago caused the mountain to collapse inward over time, forming a volcanic crater, the park says.

The average depths of Lakes Baikal and Tanganyika are deeper than Crater Lake; however, both have basins that extend below sea level." [20] [22]
Although snow covers Crater Lake National Park for eight months of the year (average annual snowfall is 463 inches (1,180 cm)), the lake rarely freezes over due, in part, to a relatively mild onshore flow from the Pacific Ocean. The last recorded year in which the lake froze over was in 1949, a very long, cold winter.
Little Crater Lake is considered an oddity, with earlier geologists theorizing it formed from a collapsed lava tube because of its steep and overhanging walls.

Lake Wawasee is the largest natural lake in Indiana, while Lake Tippecanoe is the deepest lake, reaching depths of over 120 feet (37 m). Both lakes are located in Kosciusko County. Chain O' Lakes State Park, located in Noble County, contains 11 lakes, 8 of which are connected by natural channels.
