Fulgurite is a natural glass formed when lightning strikes sandy soil or dunes. The extreme heat from the lightning fuses the sand grains, creating hollow tubes or branching structures. It is also called petrified lightning, fossilized lightning, or lightning rock.

Fulgurites are naturally formed in places like the Sahara Desert in Morocco, where the combination of vast sandy landscapes and frequent storms creates perfect conditions for their development. These fascinating formations vary from tiny, delicate tubes to larger, complex branching shapes. Made mostly of silica—the main component of sand—they form when lightning strikes, heating the sand to around 30,000°C (54,000°F) and instantly melting it. This process fuses the sand and preserves the detailed shapes and textures of the surrounding grains, offering a remarkable glimpse into natural lightning’s lasting effect.
