Rock window that originated by selective basalt exploitation southwards from Kuøívody
Old forgotten basalt quarry at one of many forgotten places of former military range Ralsko should compete with sandstone rock labyrinths if we consider it's spatial composition and variability. The quarry did not become one large pit, but it has turned into a maze of small quarries, abris and narrow passages thanks to selective basalt exploitation, only most useful parts of the masif weere mined. Under the very top, a high double rock window look to the largest pit.
