Fulgurite.
Fulgurites are like Lichtenberg figures at the other end. Lichtenbergs are formed when electric charge is gathered up from a large space and concentrated down into an arc. Fulgurites are formed when a bolt of lightening strikes the right kind of sandy soil, where it spreads out in a dendritic way fusing the sand into a glassy material. So while Lichtenberg figures freeze the gathering process, fulgurites freeze the dispersal process at the other end of the lightening bolt.
Another difference is that while Lichtenberg figures are formed in a laboratory using electric charges millions of times smaller than real lightening, fulgurites are formed by real lightening out in nature. They quite rare and hard to find.
