Chile's Marble Caves feature intricate patterns shaped by erosion

Chile's Marble Caves, located on General Carrera Lake in Patagonia, are known for their intricate marble patterns, natural arches and turquoise waters. Shaped by erosion over thousands of years, the formations can be explored by boat or kayak. Located in Chile's Aysén Region, the lake's glacial origin means its waters remain close to freezing temperatures.
