History
A former limestone quarry where the basin of the quarry has filled with water and the limestone quarried here has turned the water into a turquoise blue. The attractive turquoise blue colouring of the water is caused by the surrounding limestone rocks which leach calcite crystals into the water. The alkalinity comes from calcium oxide, a white powder which would have originally been left around the site as a by-product of the quarrying process. The limestone from the quarries in this area have been used for roadstone, building, smelting flux and lime. Some sources state the water is over 60 feet deep..
