The image is a close-up of a rock surface with a grid-like pattern. The rock appears to be old and weathered, with cracks and crevices visible on its surface. The pattern is made up of various lines and shapes, including a cross, a line drawing, and a line of text. The lines are arranged in a diagonal line, with some overlapping each other. The text is written in a cursive font and is not clearly visible. In the bottom right corner of the image, there is a small black and white checkered scale, which is likely used to measure the size of the rock.
