Fair Use rationale: the closing 3 minutes of the March 23, 1987, CBS Evening News is reproduced free of charge in the context of a collection of associated video podcasts under provisions of the "Fair Use" doctrine in U.S. Copyright Law (copyright.gov/fls/fl102.html). This one is preserved for its historical value as an independent illustration of suspected ancient Celtic archaeoastronomical alignments and petroglyphic writing in southeastern Colorado and the Oklahoma Panhandle, a news story first enterprised two years earlier by this podcaster, Scott Monahan. CBS News' awareness of these finds apparently either derived directly from Monahan's one hour KRMA TV documentary "History on the Rocks" which premiered in Denver on May 7, 1985, or derived indirectly from subsequent print media stories (onter.net/scripts.html) which did not acknowledge Monahan's antecedent, copyrighted broadcast. Its neutral perspective on the status of research in 1987 justifies this archival record as "Fair Use" in a scholarly context. Otherwise publicly unpreserved, any repurposing of this video may infringe CBS' rights.
