volcanic lake
Volcano's flooded basin
A volcanic lake is a body of water that forms in a volcanic crater, caldera, or other depression created by volcanic activity.
The water typically accumulates from rainfall, groundwater, or melting snow.
Some volcanic lakes are acidic or thermally heated by ongoing geothermal activity beneath them: The volcanic lake's turquoise color comes from dissolved minerals.
