Many of the lines are random and seem to have no pattern to them.They are seen over the scattered seemingly at random over the desolate plain, crossing and intersecting for no apparent reason.These factors, combined with the existence of a lighter-coloured subsoil beneath the desert crust, provide a vast writing pad that is ideally suited to the artist who wants to leave his mark for eternity.
Many of the lines form geometric figures: angles, triangles, bunches, spirals, rectangles, wavy lines, etc.
An example of this is the drawing of a weird being with two enormous hands, one normal and the other with only four fingers.
Also represented are drawings of man-made objects such as yarn, looms and “tupus” (ornamental clasps).
Other lines form concentric circles converging with or emanating from a promontory.
Other prints have formed “roads” like geometric planes and appear to have been occupied by large groups of the population.
