Dominica’s Boiling Lake, the second-largest hot lake in the world, is actually an opening or a hole in the earth’s crust; it is around 76 metres across. It is filled with bubbling greyish-blue water at temperatures of around 90°C. The lake is fed by rainfall and two small streams which drain into the area. The water then seeps down to the lava and is heated to boiling point. The water is heated by a continuous flux of steam or gas generated by molten lava below. Geologists believe that the lake is suspended above the local water table, which explains its rapid draining and refilling.
