I spotted this quartet of climbers standing on a high ridge under an enormous cloud. The scale of the ridge and cloud, compared to the size of the climbers, is massively incongruous. Cajas National Park, about 20 miles west of Cuenca, is in the Andes Mountains. Parts of it soar to nearly 15,000 feet. It gets nearly 3 feet of rain a year, providing 60 per cent of Cuenca’s drinking water.
