Geology

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.[2] Later geologists believe it originated from a volcanic maar[3] or was created from block faulting.[4] Artesian water from an underground spring fills the resulting depression with water. The lake was named after Crater Lake, also in Oregon,[5] due to their shared blue waters.[6] The water in Little Crater Lake is a constant 33.3 °F (0.7222222°C).[1]
