The image shows a close-up of a piece of sand with a ruler on the right side. The sand appears to be a light brown color and has a rough texture. On the left side of the image, there is a small indentation in the sand. The indentation is in the shape of a letter "H" and is slightly larger than the rest of the letter. The ruler is white with black and white markings on it. The image is taken from a top-down perspective, looking down on the sand and the ruler.
