Ancient American Inscriptions Plowmarks or History?

A critical discussion of claims that certain rock engravings in North America were made as much as 2000 years ago by visitors from Eurasia & Africa. Up-to-date analysis with 400 references by authors with backgrounds in physical sciences who spent a decade & travelled 250,000 miles to record & compare known indigenous & apparently exotic petroglyphs. Includes scientific dating of engravings, discussion of common errors of interpretation & of hoaxes investigated by authors. Highlights new discoveries in canyons of Colorado & Oklahoma now being cataloged by archaeologists. Some of these petroglyphs have archaeoastronomical content apparently reflecting world views differing from & predating those of the later Plains Indians. Explains why most professional scholars avoid involvement with amateur investigators of "inscriptions" & recommends steps to initiate more informed dialog & promote mutual understanding. Essential reference work on problems & progress of epigraphic aspects of diffusionist research & reasons for emotional controversy over this subject.
