Thick chalk deposits exist in several parts of the world, including Europe, Australia, and the USA. The bulk of this chalk is considered to belong to what is referred to as the "Upper Cretaceous" period. Geologists working within a framework of uniformitarianism (or actualism) claim that they result from millions of years of accumulation of coccoliths. If we are to take the new understanding of the age of the earth from RATE studies seriously, then it is necessary to explain the chalk by mechanisms which do not involve such long timescales. Snelling (1994) attempted to explain the chalk deposits within a timescale of a few days, so that chalk could be considered as part of the visible evidence for the Noachian Flood. Tyler (1996) then tried to show that the model proposed by Snelling was not tenable and described how chalk had to be interpreted as a post-Flood deposit, but within a short timescale. This document shows two things. First, that the certain features of the "Upper Cretaceous" period correspond closely with the biblical account of the Noachian Flood around day 150. Second, that uniformitarian explanations for "chalk" are inadequate to explain their deposition, reworking, and geomorphology and that only by considering the rapid events in the middle of the Noachian Flood can their deposition and characteristics be explained. En passant we make two additional discoveries, viz (i) that the concept of the geological column is not robust over small distances, and (ii) that there is independent support to the RATE studies that show that the earth is young. A consequence of this geoscientific study is that geology is a powerful visible witness to the testimony of the Bible, and such facts should therefore be used in evangelism. Specifically, the real fossil record, rather than the constructed geological column, disproves evolution. The geoscience also shows that active promotion of what was commonly known as the European Recolonization Model (or its variants where the bulk of the strata are judged to be "post-Flood") to explain geology was ill-founded.
