The engravings are in an extensive and flat granite slab that appears on the surface of the terrain, in the rising edge of the knoll, with a wide view on the valley of the Terva River.
Two motifs are distinguished, separated from each other by about 3 meters and recorded by pecking and abrasion. To the south a more simple, quite eroded and to the north a more complex, well maintained.
The first corresponds to a circular figure, composed of the rest of two concentric grooves. The second is also a circular figure, which is organized around a small elevation of the outcropping, at the top of which a circle, completely filled by dimples, has been grooved, marking the center of the composition, followed by two equally grooved concentric rings and finally a sequence of four rings, also concentric, formed by aligned dimples.
