Altocumulus lenticularis duplicatus, also known as 'pile d'assiettes', forms when stable, moist air flows over a large obstacle such as a mountain, creating waves that cause the clouds to form at the crests. In this classic example, there are multiple, stacked layers of these lens-shaped clouds, spotted over Torres Del Paine National Park, Patagonia, Chile.
