The image is a close-up of a tree trunk with a rough texture. The bark of the tree is dark grey and has a rough, textured surface. In the center of the trunk, there is a large, circular indentation in the bark. The indentation appears to be made up of small, jagged rocks or boulders. The rocks are arranged in a symmetrical pattern, with some overlapping each other. The overall appearance of the image is rough and uneven.
