Well, Bob, a Hershey bar. Yes, eaten by ants .. sounds right. I think you
are right also regarding the magnetite. Though, it is supposed to be
magnetic, I have not noticed that. But, indeed, the stuff near the Golden
Gate Bridge is black in some places. By taking the magnet and running it
through the sand one can gather quite a bit in a few moments. I've always
been into 'natural' occurring stuff and was really happy to have thoughts to
use it in my photograms. It is part of my fiddle around, have fun and make
history routine of life in photography.
Best
Jack
