This winter will be archeologically most active until now. Three teams of the ‘Archeological Park: Bosnian Pyramid of the Sun’ Foundation work on three locations of the Ravne Complex tunnels. Two locations are located on the Foundation’s plots, and on the third Foundation has a long-term contract.
Lighting is set in all locations. A team led by an experienced miner worker to place a protective wooden supports at all three locations. Along with the use of protective equipment, the Foundation workers are removing filler gravel material from the sealed tunnels.
In the ‘Ravne 3’ location, instead of the classical entrance tunnel, bigger galleries were discovered. The two main directions of the tunnels are East-West, below the settlement of Dubrava, and North-South, parallel with the Underground Labyrinth Ravne.
In the tunnel ‘Ravne 3’, concentration of negative ions were measured. While the value is outside the tunnel 150 of the negative ions per cubic centimeter, the value in the tunnel entrance is 900 ni/ccm, which is five times more. When tunnels were discovered at a depth of 65 meters from the entrance, at the end of August 2018, the value of the negative ions was 10.000 n / ccm. This is beneficial value for the human health.
