No. 18: Nov-Dec 1981
In 1980, P.M. Leonard and J.L. Glenn, from the Hogle Zoological Gardens, Salt Lake City, visited a rock outcropping in Colorado that was reputed to be inscribed with 'peculiar markings.' The markings were peculiar all right, for Leonard and Glenn believe they are excellent examples of Consainne Ogam writing, a type ascribed to ancient Celts. Translation by B. Fell suggests that the Colorado site was a shelter for Celtic travelers long before Columbus! One of the many inscriptions was translated as:
"Route Guide: To the west is the frontier town with standing stones as boundary markers."
(Leonard, Phillip M., and Glenn, James L.; "A Celtic Frontier Site in Colorado," Epigraphic Society, Occasional Papers, vol. 9, no. 223, 1981.)
Comment. Although the Colorado Ogam cannot be written off as plow scratches, as it is in the eastern states, one should be aware of the highly controversial nature of these claims for Ogam writing in North America.
