Signal discussion- signal at Shawsville

[NW Mailing List]

To go along with the signal discussion of a few months ago, I attach this
signal near Shawsville that is from a 616 contact print with H Reid
scrawled in green ink on the back.  No date.   So, how was this signal
used?  Note the lower head.
