The image shows a close-up of a sandy surface with a small footprint in the center. The footprint appears to be made of small rocks or pebbles and is in the shape of a letter "A" with a curved line running through it. The background is a light beige color and there is a black and white striped ruler next to the footprint. The ruler has the word "cm" written on it in black letters. The image is taken from a top-down perspective, looking down on the footprint and the ruler.
