In a 1983 issue of the Quarterly, a creationist geologist published a carefully prepared and well-researched treatise on the stratigraphic separation of fossils (Woodmorappe. 1983, pp. 133-185). In marked contrast to many previous Flood models which proposed mechanisms and processes that were rather simplistic and largely not compatible with the actual layout of the rocks and the fossils they contain, John Woodmorappe's concept appears to overcome most of these incompatibilities. It has been both surprising and disappointing that this model has been almost completely ignored by creation scientists and others, possibly because of its grand scope and consequent complexity. This paper evaluates, simplifies to a limited degree, and elaborates on Woodmorappe's Flood concept and thereby hopes to encourage more debate and interest in the field of diluviology and geology, for unless creationists can suggest a reasonable and consistent explanation for the earth's rock systems and the undeniable separation of fossils, the evolutionary uniformitarian approach to geology will continue unchallenged in its domination of earth sciences. This paper (Part I) will discuss the precision of the geologic column. A later paper (Part II) will evaluate the Woodmorappe Flood model.
