A lightning strike can also create a large Lichtenberg figure in grass surrounding the point struck. These are sometimes found on golf courses or in grassy meadows. [12] Branching root-shaped "fulgurite" mineral deposits may also be created as sand and soil is fused into glassy tubes by the intense heat of the current.

There are several natural processes that produce more or less melted sand and one man-made form: Fulgurite is sand fused by a lightning bolt hitting sand.
