Marble caves

Las Cuevas de Mármol (The Marble Caves) sit in the middle of General Carrera Lake, which lies between Chile and Argentina. The tunnels and caves are only reachable by boat. The swooping arches have been formed by more than 6,000 years of water lapping against the rock, and the waters change color depending on the time of year.

The flight

A condor flies toward a rainbow forming in the spray of Iguazú Falls. The falls, located on the border of Argentina and Brazil, plunge a remarkable 269 feet and are among the world’s most picturesque. “Beauty and the power of nature take the breath away,” photographer Tomasz Tyrka says of the scene. “The cascades with condors flying above made perfect composition. I quickly grabbed the camera to capture this wonderful spectacle.”
