Here is the marvelous Marble Caves (Cuevas de Mármol) in the Patagonian Andes of Chile. It's not easy to reach this peninsula of solid marble bordering a remote glacial lake that spans the Chile-Argentina border. After a long journey, we finally arrived at the quiet village Puerto Rio Tranquilo. I shot this picture from a boat left from the village's port. And I have more close-up photos to share of course! :)
