Lightning Damage to Distributon Poles

We received these pole photos from Newfouldland recently and are wondering how prevalent this type of damage is. If you have experienced this type of lightning damage let us know... Jonathan Woodworth

Mystery Photo - Created by Nature

Recently while walking the beach on the Atlantic coast in South Florida, we came across these rocks that had just been washed ashore. At first we thought they were just a neat ocean formation, but after looking more closely, we believe them to be fulgurites.

Fulgurites are hollow tubes that are formed in sand or soil by lightning strikes. They are formed when the high temperature generated by the lightning strike instantaneously melts silica and fuses the grains together. Fulgurites can also be produced when a high voltage electrical distribution network breaks and the lines fall onto a conductive surface with sand beneath. They are sometimes referred to as petrified lightning.

The tubes can be up to several centimeters in diameter, and meters long. The longest fulgurite found is a little over 4.9 meters in length, and was found in northern Florida, USA. Their color varies depending on the composition of the sand they formed in, ranging from black or tan to green or a translucent white. They are root like in appearance and often show branching or small holes.

We have searched for other explanations and to date have not found any. We welcome any comments. Jonathan Woodworth
