Parinacota Volcano and Llamas at Lauca National Park, Chile
This photo shows llamas at Lauca National Park in Chile. The dormant volcano, Parinacota, rises in the background, its peak fully covered in snow. Taken in June, this photos was taken during the southern hemisphere's winter, but this volcano actually lies close to the northernmost point in Chile, fully in the tropics; the cold here is attributable solely to altitude.
