Alfred Watkins of "ley line" fame had a theory,later dropped,that the alignments he detected were pathways of ancient man,some of which were used for trade routes,principally salt. he came to this conclusion because of the reoccurance of the word "salt" and its ancient equivalents in the places and roads on his pathways. it would be interesting to know if anything similar occurs in America,especially on old paths connected to this site.
