The image is a photograph of a plaque on a stone wall. The plaque is rectangular in shape and has a beige background with black text. The text on the plaque reads "Potholes" in French. Below the text, there is a description of the potholes, which are trapped and spinning under water's direction, particles of sand, silt and gravel, and a diamond drill. The river took thousands of years to drill the river to the canyon walls, now suspended on the walls. The pothole you see forming today will one day be suspended on a wall of an even deeper canyon.
