The horizontal levels of stones form like plateaus which are similar but less deep than the step pyramids we see in Mexico for example.
Some levels are bigger with bigger stones and a drop of up to 10 metres. Other levels on the same pyramid will be smaller with smaller stones and less denivellation.
In Ostrets there is one level at the elevation of 880 metres which is clearly visible from a distance that marks a 10 metre denivellation. It is so important that it seems to act as the original base of the pyramid.
In Ostrets there is a lower base for the pyramid from 660m to 880m and then an upper pyramid from 880m to 1029m at the summit.
At the Black Peak complex of megalithic sites we find levels like borders made from large granite stone blocks cut at right angles. These levels are several hundred metres long. In some areas they have been washed away by millenia of water damage and erosion.
The Pyramid of Stryama has 5 levels of orizontal stone lines on the South side plus the summit.
At the Double Pyramid of Bania there are on each pyramid up to 5 distinctive levels between the base andthe summit.
Multiple levels of stones
In Rozovets we find levels at stones formations like the Standing Stones and the Tetrahedron. Both have 5 levels of stones in their constructions.
We are currently organising a funding campaign for LiDAR scanning system that will provide exact measurements of the pyramids. It will reveal the number of levels and their gradients at each pyramidal formation.
