We propose a method using suites of criteria to help establish pre-Flood, Flood and post-Flood strata. Our method is independent of chronostratigraphic indicators (that is, radioisotope dates and zone fossils); instead it relies on other criteria. Application of this model is made using the lithostratigraphic section from Wyoming and vicinity (USA) as an illustration of how the criteria model should be used. Not only can this model be used to help more confidently determine Flood boundaries, but it might be used as a test to see whether we can rely on chronostratigraphic or biostratigraphic units to determine Flood boundaries elsewhere. Properly understanding which strata belong to the pre-Flood, Flood, and post-Flood periods by recognizing large-scale patterns or suites of criteria, will help us more fully understand the biostratigraphic patterns found within the rock record.
