Wet sand features bumpy tracks and surrounding beach debris.
A top-down view of wet sand on a beach. A few dried leaves are on the bottom, in the middle. The sand has a track of bumpy, round lines sticking up on it going across and around in different directions in the middle. The lines are all connected. Part of a green weed is visible on the right, going across to the middle. A clump of sand is on the top left, near the end of the weed.
