The Rebersburg Fulgurite!
The Rebersburg Fulgurite was discovered near Rebersburg, Miles Township, Centre County, Pennsylvania in November 2015. The result of a massive lightning strike, the fulgurite formed what can only be described as an obsidian tree, wide at the base with a diminishing diameter farther from the initial strike, with bifurcating branches along the main trunk. It extended approximately 16 feet in length, with at least five branches, each up to 4 feet long. The base of the fulgurite trunk is over eight inches in diameter and comprised of a solid black glass core with a vesicular rim. Specimens from the fulgurite range in size and composition from the site of the impact to the ends of the branches. The largest intact piece is solid glass, approximately sixteen inches long and weighs nearly twenty-five pounds. Along with two other adjacent pieces, they form an impressive specimen nearly twenty-two inches long that weighs over forty-five pounds. Most pieces are between two to five inches, comprised mostly of vesiculated glass with embedded rock on the exterior. Some contain extremely rare iron silicide nodules up to 1cm in diameter. Analysis on the silcides is ongoing. The extremely rare mineral Gupeiite, previously thought only to occur from extraterrestrial sources, has already been confirmed. This is the largest fulgurite ever discovered in Pennsylvania and it may well be one of the largest fulgurites discovered in modern times. Its historical value is without question.
