Crater lake. View of the Pulvermaar crater lake. This ancient feature,a maar lake,is the remnants of a long-extinct volcano. Maar craters form when molten magma rises from the Earth and meets surface water or ice,causing massive steam explosions. They are nearly always roughly circular in shape,as here.
