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]
