Turquoise-blue waters of Lake Argentino surrounded by the snow-capped Andes Mountains

iss074e0573516 (May 6, 2026) --- Turquoise-blue waters of Lake Argentino are surrounded by the snow-capped Andes Mountains in Los Glaciares National Park in Argentina's Santa Cruz Province. Multiple active glaciers feed the lake with their finely ground glacial sediment giving the lake its striking turquoise‑blue color.
