In the late 1980's some of the bones were dated by a UCLA lab, yielding an age of 210 +/- 70 years (Berger and Protsch, 1989). Shortly thereafter Arthur Strahler (1989) published his book Science and Earth History, a chapter of which recounted the Moab Man saga. Later carbon dating tests on more recent excavations from the mine in the early 1990's yielded dates of 1450 +/- 90, with a calibrated one-sigma date range of AD 540 to AD 670, suggesting that the mine had been used by native Americans for at least several hundred years. (Coulam and Schroedl, 1995). However, the dates are consistent with intrusive burials, and contradict claims that the bones were part of the Mesozoic, Dakota Sandstone host rock, dated at approximately 100 million years by mainstream geology. Further corroboration of Marwitt's analysis is found in a draft of a book by researchers Eckert and Eckert (1979), who were dismayed by the failure of Burdick and other creationists to depict the Moab Man evidence fairly and accurately. For several years afterward the case seemed to be largely abandoned by most creationists.
