On a high mountain ridge in the rugged Himalayas of Ladakh, India, a camera trap captures a snow leopard (Panthera uncia) marking the highest point of a rock with its cheek pheromones. This behavior acts as a logbook, allowing other leopards to track the movements of this elusive big cat. The title of the image, ‘Ghost of the Mountains’, reflects the snow leopard’s elusive nature. Masters of camouflage, these creatures are rarely seen in the wild.
