This is a photograph of the Atacama desert. The image is filled with a barren, brown ground surface that has very little structure apart from some polygonal patterns made from cracks in the middle ground. Around the cracked area there are large rocks, casting their shadows in the bright sunlight. The rocks are of various sizes and most have sharp edges and are of angular forms. One area in the foreground is covered in very small, dark brown nodules.
