The erosion eye is a rock, on the heights of Baumayrane, offering a fine example of taffoni;(word of Corsican origin meaning "hole"), common phenomenon around the Baux-de-Provence. Its cavities dug by erosion can have very different shapes and sizes, depending on the structure of the rock and its ability to absorb water. Here, the erosion eye is pierced through, allowing to see through.
