Fulgurites are fossilized lightning strikes. The intense energy from a lightning strike essentially melts the ground. Lightning strikes can fuse rock, clay, or sand into fulgurites shaped like irregular hollow glass tubes. Physicist Don DeYoung wrote in 2013 in the Creation Research Society Quarterly that after 4.6 billion years, at the current lightning strike rate, every square meter of land should contain far more fossilized lightning strikes than it can even hold. New fulgurite research updates the numbers to bring this fulgurite problem into sharper focus.I hope it strikes your fancy to finish reading this short article.

Two Florida geoscientists collected and measured over 250 recent and ancient fulgurites from Polk County, Florida. In the online journal Scientific Reports, they published a way to estimate a lightning strike's energy by the dimensions of the fulgurite it produces.
