Fulgurite is a type of natural glass formed when lightning strikes sandy soil or dunes, creating a remarkable geological phenomenon. The extreme heat generated by a lightning bolt fuses sand grains, forming hollow tubes or branching structures known as fulgurites. Often referred to as “petrified lightning,” “fossilized lightning,” or “lightning rock,” these formations capture the raw power of nature in solid form.

The Sahara Desert in Morocco is one of the notable regions where fulgurites are found. Its vast stretches of sand and occasional thunderstorms provide ideal conditions for their formation. Fulgurites can vary greatly in appearance—from small, delicate tubes to larger, intricately branched patterns—each one a natural record of a single lightning strike.

Fulgurites are composed mainly of silica, which is the primary component of sand. When lightning strikes the ground, temperatures can reach up to 30,000 degrees Celsius (54,000 degrees Fahrenheit), causing the sand to melt and fuse rapidly. The resulting fulgurite structures preserve the shape and texture of the surrounding sand grains.
