Right beside the lateral moraine of Patagonia’s Perito Moreno Glacier, natural dams of ice and rock are occasionally formed. Thanks to glacial-fed rivers and streams, these often give rise to small lakes.
When the water pressure finds a crack, a slow process of ice boring begins. Thus, little by little, these caverns are sculpted underneath the glacier. When the lakes are emptied completely, for a brief period of time it is possible to explore these ephemeral and psychedelic ice galleries.
