Fulgurite is a type of natural glass formed when lightning strikes sandy soil or sand dunes, creating a fascinating geological phenomenon. The immense heat generated by a lightning bolt fuses the grains of sand, producing hollow, glassy tubes or branching structures. Often called petrified lightning, fossilized lightning, or lightning rock, fulgurite captures the raw power of a lightning strike in solid form.

The Sahara Desert in Morocco is one of the regions where fulgurites can naturally form. The desert’s vast stretches of sand and periodic thunderstorms provide ideal conditions for their creation. Fulgurites vary greatly in appearance — some are small and fragile, while others display complex, tree-like branching patterns.

Composed primarily of silica, the main constituent of sand, fulgurites are created when temperatures soar to around 30,000°C (54,000°F) during a lightning strike. This intense heat causes the sand to melt and fuse almost instantaneously. As the molten material cools, it solidifies into a glassy structure that preserves the texture and shape of the original sand grains, forming one of nature’s most striking examples of energy captured in stone.
