Exogenic Fulgurite "Burning Bush" Museum Grade
Exogenic Fulgurite "Burning Bush" Museum Grade, Elko Hills, Nevada
When lightning strikes the earth's surface and melts the materials it contacts, the remains are collectively known as fulgurites. Their classification has generally been limited to forms that form below the surface of the ground as soil, rock, sand, or clay fulgurites. In 2004, there was the first documentation of "exogenic fulgurites," those formed from lightning striking vegetation and causing the heated, liquefied remains to be ejected into the atmosphere. During their descent, while cooling, these remains often took on a similar shape to the original material.
So why aren't these more common? Although "a lightning strike" is commonly used to describe all lightning, only about 25% of all lightning events worldwide are cloud to ground. The other 75% is cloud to cloud OR inter-cloud.
Perhaps most exogenic fulgurites, when found, can also be misinterpreted as anomalous material and randomly discarded. This might be why there is not much talk about them or more "finds," as most people are not aware of this form of them.
The odd contortions and shapes of these specimens make them an interesting addition to serious collections that contain geological oddities. This material makes an interesting and real scientific contribution to our understanding of lightning's action on above ground materials.
This is a fantastic, very detailed and unique specimen.
