Rising from the heart of a mountain-ringed valley known as the Tularosa Basin is one of the world’s great natural wonders – the glistening dunes of the Whites Sands National Monument. I made this image of them at sunset, anchoring the image with two golden crowns of desert grasses. At this time of day, the interplay of light and shadow on the dunes is constantly changing as the sun drops below the mountains surrounding the Tularosa Basin.
