Exogenic Fulgurite   Oswego, Oswego County, New York.  From lighting strike on August 2, 2008, ref. Rocks and Minerals magazine, May/ June 2011 issue, vol. 86, no.3, p. 264-270.  Collected by Joeseph, Jonah, Arlo, and Jeffery Shallit.  An 11 x 11 x 4.5 cm specimen of very complex composition.  This piece is from the rim of the primary evulsion crater.  It is shaped like a wave of water cresting near a beach.  One side (the outside) shows soil contacts while the inside is relatively smooth.  Lots of interesting structures including balls to almost a cm each, filaments too numerous to count, tadpole like forms, as well as others.  This is one of the more important pieces created at this important occurrence.  Edge contacts from the rest of the evulsion crater and filaments that are incomplete, as would be expected.  Fantastic example of this rare material.  Very large, complex and interesting.  A real conversation piece!   $950 (on sale for $760)
