Stone quarry rock face of Bochniky

Unique Stone quarry rock face rock cliff of Bochniky hill (CZ) with a meadow and footpath The open, semi-circular area of the former quarry is framed by 6-8 m high columns of tephrite up to 1 m thick, some with curved and narrowed uppermost parts and with a powerful conical envelope of tephrite tuff. Theories differ as to what causes this curvature and narrowing. One gives as the reason the morphology of the terrain on which the lava flow poured, another speaks of the solidification of the melt surface with the simultaneous movement of unsolidified matter within the flow. All the columns, due to the detachment of the rock, are fairly regularly split transversely, thus splitting into individual prisms, rounded by weathering, giving the impression of stacked loaves of bread. http://www.ceskestredohori.cz/mista/konojedske-bochniky.htm Photogrammetry scan, 3x8K textures, DSLR by me + drone by sketchfab.com/kubacpetr
