The rock with drawings of "space-ships" near...

On a rock, 2.60 meters long and sticking out of the earth for about 1.2 meters can be seen marking in the form of an ellipse with lines about a centimeter in depth and two centimeters wide. Its' about five hndred meter contour in a small wood on the western side of the 'crest" of Sant' Antonnino di Susa is a rock with markings that resemble a series of spaceships. Does anyone know if that rock is still there or has it been removed? Aime Michel speaks of this rock.
