Lake Eacham a popular tourist lake of volcanic origin on the Atherton Tableland of Queensland, Australia.
Lake Eacham and the nearby Lake Barrine, were formed approximately 12,000 years ago by molten magma. Magma from the center of the earth rose to the surface and heated the water table. The steam that resulted from the boiling water was trapped underground, until massive explosions signalled its release. Huge cracks appeared in the ground and the trees that once lathed the mountainside were levelled and burnt.
Eventually, over hundreds of years, water filled the craters and the trees grew back, creating the tranquil lake used today by families and tourists for recreation. The lake is fed by underground springs so it maintains a constant water level and is unaffected by drought.
