What is a Fulgurite?
A fulgurite is often referred to as "petrified lightning".
When lightning strikes the sand,the heat fuses the sand into fascinating structures. The long, slender glass tubes are belowthe surface of the sand and can be found bylooking for uneven coloring on the sand’s surface where the lightning has entered.The glass structure is usually an irregularshape and is not transparent but has a greenish cast from the hue of the sand.
The very brittle fulgurites break easily while removing them from the sand. Each fulgurite is different and can have a main branch and then many smaller branches that resemble the actual flash of lightning. Some fulgurites are round and hollow while others are flattened into rough shapes caused by the pressure of the sand.
