Fulgurite (Fused on Sandstone) Oswego, Oswego County, New York. From lighting strike on August 2, 2008, ref. s and Minerals magazine, May/ June 2011 issue, vol. 86, no.3, p. 264-270. Collected by Michael R. Walter, August 25th, 2008. This was a rare find at this particular strike and an interesting conversation piece. Seen here is a fulgurite solidly fused to the edge of a smooth sandstone pebble. Again, rare at this strike (and very rare in general) because the soil where it occurred was dominated by organic material and very fine grained rock particles. The fulgurite is hollow and branches off in two directions.  As can be seen in the images, the heat from the lightning strike was intense enough to extensively crack the rock without blowing it apart.  All natural and withut damage.  4.5 cm. $350
