Re: "fulgurites"
My neighbor's driveway shows a whole bunch of similar artifacts,
deeply melted into the concrete, which resulted from a fallen 2200 volt
transmission line lying on the ground and arcing for a few minutes..
Happened some time before we moved here 26 years ago, but after
the neighbor lived there. Until I pointed them out to him he never knew
what they were, and just reported that "they appeared one morning after
a wind storm took our power out for a while". The traces are "frozen
lightning", some a half inch wide and many inches long, completely
vitrified.
