Fulgurite - Sand hit by lightning. This picture is not Fulgurite by the way.This is a stick with wet sand on it.Fulgurite is usually found in the ground where lightning has struck and is usually very small glass tubules.
We had a fantastic lightening storm last nite, Aug Booms, low rumbles, actual lightening bolts (not the typical sheet lightening). Haven't had a good one in SW Puget Sound for years. a really good picture of an amazing set of lightning strikes.
