Check out this amazing drone video of the largest freshwater lake in the South American country of Argentina. Argentino Lake is located in the state of Santa Cruz, which is part of the Patagonia region in the southern part of the country. The lake covers over 1.6k square km (about 550 square mi.) and is quite deep - about 500 meters (1.6k ft.) at its deepest point. Let's Fly Production used a drone to create this beautiful video of the great lake and neighboring city of El Calafate.
