Bosnian pyramids: Photos of the ravne tunnel complex

You see to the right of the photo is another dry stone wall within the tunnel fill which was excavated that day.
These walls indicate to us that the tunnel fill could not have been a natural deposit because dry stone walls dont form in natural deposits!
The Drywalls are positioned at intersects along the main passage where smaller side passages branch off. These are also filled in the same way as the main passageway. The material is unconsolidated and can be pulled from the tunnel walls quite easily.
The board on the floor protects various stones which are below. Larger boulders are placed along the floor of the tunnel at various positions. The actual tunnel floor is 30cm below what we are working on.
The position of these stones almost certainly has some importance and must be studied further.
These are the typical objects that get pulled out daily from the tunnel fill material
Much of this material here is either shaped stone or an artificial composition ie concrete.
Similar material can be identified in situ on the moon pyramid. This could indicate that the tunnels were filled in after the construction of the pyramids. Someone may have filled the tunnels with all the waste material. As you can see much of the material is broken and eroded bricks/tiles.
The white ball of material in the left corner is a sandy limestone. This material may have been used for the creation of a binding agent in the concrete.
The dark coloured artifact (Bottom, centre-left) is part of a larger slab made up of 4 pieces in total.
Each piece was pulled out in close succession over 2 days. There are markings across all four pieces. Someone had broken the complete slab and then buried it within the tunnel.
Here you can see the clear difference in colour between the natural post glacial deposit the tunnels are cut into and the material filling the tunnel.
The tunnel fill is a mix of unconsolidated sand, bands of clay and mixed sized boulders. Orientation of the stones and boulders are random. There is no preference for orientation as there would be if the material were deposited by water.
This and the fact there are dry stone walls within the fill gives us confidence in the idea that the tunnels were purposely blocked up.
The next step is to figure out whether it was blocked up from the outside, or from the inside.
Here is an interesting artifact!
Look closely and you can see the head is that of a bird.
