What is a crater lake?
Quick Answer
A crater lake is a lake that fills a volcanic crater or caldera. It forms when rain, snowmelt, or groundwater collects in the bowl-shaped depression.
The Full Story
Crater lakes are created in volcanic basins left after eruptions or collapse. Because they often sit in enclosed depressions, they can become very deep and have striking colors depending on minerals, depth, and biological activity. Famous examples include Crater Lake in Oregon, formed in the caldera of Mount Mazama, and Lake Toba in Indonesia. Some crater lakes are scenic, but others can be hazardous if volcanic gases or landslides disturb the water.
