The hill had been formed from volcanic rocks. It has a conical form with a saddle at the top and it belongs to the volcanic area Kratovo-Zletovo. The volcanic cone, the lateral secondary parasite effusions and volcanic neck (petrified lava in the lower volcanic channel) are preserved from the extinct volcano. The erupted lava is of an intermediate character with an andesitic composition, with clearly columnar (prismatic) emission and accentuated cracks.
The natural predisposition of these andesite rocks to crack vertically and horizontally caused forming of almost ideal cubic rock blocks that could be easily shaped and wisely used by the prehistoric dwellers as areas/positions for observing the movement of the Sun and the Moon and for performing religious rites..."
