Description
Big Rare chunk of fulgurite or petrified sand.
Fulgurite is the result of lightning striking the ground. This piece was formed when lightning hit the sand and clay, forming a tube structure as it traveled into the ground. Fulgurites are natural tubes or crusts of glass formed by the fusion of silica (quartz) sand or rock from a lightning strike. Their shape mimics the path of the lightning bolt as it disperses into the ground.
