Chile's Marble Caves: Nature's Turquoise Masterpiece
Originally Published 1 year ago — by Livescience.com
The Marble Caves in southern Chile are stunning natural rock formations located on the shores of General Carrera Lake. These caves, accessible only by water, feature smooth, swirling mineral patterns on their walls, which reflect the lake's turquoise waters, creating an ethereal blue light. Formed over 10,000 to 15,000 years through the erosion of limestone that transformed into marble, the caves offer a unique visual experience best explored by kayak. The lake's glacial silt gives the water its brilliant azure color, despite its freezing temperature.
