Cannon Balls. Fayoum. الفيوم Каменные шары. Файюм.

Stone Balls or "Cannon Balls" - is one of the spectacular mysteries of Nature, which can be found in New Zealand, Romania, Kazakhstan, Brazil, Russia, Costa Rica, the archipelago of Franz Josef Land, and also in Egypt. Here in Egypt, such spherical geological formations can be found in South Saqqara and Fayoum. Such nature "artifacts" are common to underwater lavas of extrusive rocks such as basalts, spilites, diabases, trachytes and porphyry. But, along with igneous rocks, the similar formations are laso observed among the sandstones.
